Enhancement: Ability to add filters

[jdlrobson]

In TiddlySpace? I would like to extend the filter syntax to recognise [is[Private]] [is[Draft]] and [is[Public]].

To be able to do this I would like a hook

A config.filters dictionary which could hold custom filter definitions would meet my needs. So in the above case I might define a filter "is" which is called with the parameter public/private/draft by filterTiddlers.

e.g.

config.filters = {
  is: function(value) {
    // get tiddlers
    return tiddlers;
  }
}

I've been working on a plugin which could be turned into a core patch if it's an acceptable approach:

-- needs more tests than the current core ones ..

I notice there are seemingly several incorrect references to "this" Should they not reference store?

e.g. this.getValueTiddlers(match[2],match[3]); should be store.getValueTiddlers(match[2],match[3])

It seems to work but I'm worried about side effects.
