Latest version to address some bugs found. 

Bugs eliminated include:

- Sprite screen now updates following an import sprite action when the menu closes.

- Tilemap Editor did not allow for local fill greater than 8192 bytes. This has been fixed to allow a full bank to be 'local' filled. Fixed.

- Tilemap Editor could not globally fill the maximum size map (16384 bytes) allowed without crashing. Fixed.

- Tilemap Editor would allow the user to define a tilemap greater than 16384 bytes leading to a crash. Fixed.
