General versatility improvements

Hi, just a few small suggestions:

1) Allow quicktext rules that apply to all languages, including unspecified/unknown.

2) Allow custom triggers so no extra keypresses will be necessary in some cases.

For example, I'd like to have quicktext automatically translate (in any language) "open brace + enter key" into "open brace, enter, enter, close brace, back key, up key, tab, make here a hotspot, make the next line after the close brace another hotspot" (working on the assumption that npp is set to preserve current tab depth).

3) Finally, tying in with the last 2, provide a convenient way to enable/disable specific rules and triggers (especially for non-language-specific rules).

QuickText looks really cool, but could be much more useful. I may take some time to peruse the source, and see if I am skilled enough to contribute such features myself, but that's unfortunately not likely.

Cheers,
