Fixed MOUSE_WHEEL event not triggering on Firefox.
Added an extra mouse matrix stack clean-up.
Removed a debug trace from BitmapData.
Corrected index.html template for consistency.

Also removed the Flambe template. There's absolutely no logical reason
to why you would want to include it alongside with this library.
Cleaned up some of things with naming.
Corrected BitmapData.setPixel* behavior with lock()

Now uses pixel plotting only if there's no ImageData to speak of.
