* Command-like searching

* search in a given text.
*
* Search syntax:
*
* | Token | Match type | Description |
* | ----------- | -------------------------- | -------------------------------------- |
* | `jscript` | fuzzy-match | Items that match `jscript` |
* | `'python` | exact-match | Items that include `python` |
* | `!ruby` | inverse-exact-match | Items that do not include `ruby` |
* | `^java` | prefix-exact-match | Items that start with `java` |
* | `!^earlang` | inverse-prefix-exact-match | Items that do not start with `earlang` |
* | `.js$` | suffix-exact-match | Items that end with `.js` |
* | `!.go$` | inverse-suffix-exact-match | Items that do not end with `.go` |
*
* A single pipe character acts as an OR operator. For example, the following
* query matches entries that start with `core` and end with either`go`, `rb`,
* or`py`.
*
* ```
* ^core go$ | rb$ | py$

*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,

*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

/*
Punishes spammers. Assigns a penalty to every message in a groupchat, and when a certain score is reached, it penalizes the user.
Options:
ignores - array of strings([]) = users that won't be penalized (trigger effectively won't see them). You probably want to put yourself here, as admins aren't treated specially. (this is a built-in)
logLevel - string(info) = what level should we log at? Choose a level from the top of chatBot.js
admins - array of strings([]) = admins that the bot tattles to. You probably want to put yourself here. This function doesn't differentiate between users and
groupchats, so you can have it report to a groupchat as well. Can be an array [sid,sid] or an object {name:id,name:id} for readability.
score - object = at what score should a certain action be taken?
score.warn - int(3) = when should we warn the user?
score.warnMax - int(5) = when should we *stop* warning the user? Defaults to score.kick-1.
score.kick - int(6) = when should we kick the user?
score.ban - int(8) = when should we ban the user?
score.ignore - int(10) = when should we add the user to the global ignore list
score.tattle - int(4) = when should we tell the admins?
score.tattleMax - int(5) = when should we *stop* tattling to admins (clearly they don't care or aren't here, don't spam them). Defaults to score.tattle+1.
msgPenalty - int(1) = how much should we add to a user's score on each message?
timers - object = timer setup. Mostly how many timer cycles should we perform certain actions after (ie how long punishments last)
timers.messages - int(5*1000=5sec) = timeout (in ms) for messages. The bot will not warn or tattle on a user more than once every X milliseconds.
Set explicitly to false to disable timeouts. Timeouts for warning/tattling are separate.
timers.unban - int(5*60*1000=5min) = when should we unban a user?
timers.unignore - int(5*60*1000) = when should we unignore?
ptimer - object = use this to control how fast the score decreases, ie if you want to reset the score entirely or just decrease it.
ptimer.resolution - int(1000=1s) = How many milliseconds between decreasing the score?
ptimer.amount - int(1) = how much to decrease the score each time?
badwords - object = assign custom score to bad words. Set a penalty to null to use the default penalty. Per-message penalty will also apply.
You'll probably want to adjust the warnMessage if you set this. For example - badwords: { fudge:10, sucks:5, "eat me":null }
TODO: Use cache to save punishments and revert them during onload; don't keep punishments if the bot crashes
debug - bool(false) = should we spam your log every time we reduce scores? Turn this on if you think something's not working right.
