Added formatParse to FlxText: t.text="show $green text$ between dollar s...

...igns"; t.formatParse([greenFormat],["$"]);

(Trying this again)
Probably a crash. Let me throw in some explicit errors if that's the case. formats.length should always == markers.length or else user intent is ambiguous.

If the case of one of the entries being null:
  - If a marker is null, right now the corresponding format is probably ignored
  - If a format is null, a crash will probably happen
