What's New:

ARM Developer
- debugging window added for global variable inspection
- collision detection of ARM stack with program variables
- static areas window improved
  * clearer indication of memory addresses
  * labeling of named variables in memory
- performance window improved
  * raw ARM cycle values in addition to percentile values
  * kernel focus (VBLANK, Visible Screen, Overscan)
  * performance relative to frame
- access of address 0x00 is treated as illegal (probably null dereference)

- BREAK NONEXE to halt execution on 6507 execution if PC address is not in the Cartridge or RAM areas

Debugger GUI
- better window management in the debugger
- window state (open/close) saved between sessions

Playmode GUI
- non-integer scaling reintroduced - improved scaling method to avoid uneven scanlines
- bugfix (Windows and MacOS)
