Fixed a small display bug in the sprite editor when changing mode
Fixed a stack underflow bug when local arrays of bytes/bools go out of scope
Fixed an assignment target error for indexed custom type array
Fixed a bug in the keyboard ISR. Several keyups were being registered for a key instead of a single shot
Added a int2txt utility function in /UTILS/
ImageEd updates:
New larger Zoom window. The unzoomed view now follows the zoomed one.
Undo (FCTN + U) and reDo (FCTN + D) functions implemented. 'Unlimited' (up to 999). A bit slowish because it is file based, but ok in most cases. Will be improved later for brush strokes with a local cache.
Major compilation time reduction. Almost 2x faster to compile than with previous versions.
Added support for post inc/dec ops on members of custom arrays types to the compiler. e.g. vec2Array[n].y++;
