- tiny updates for better behavior, unix line endings, cvs Id tags;
- Updated DX7 exporter (thanks to author Ben Omari who's also working on a DX8 one);
- added sysinfo script;
Interface (scripts):
- changed behavior for which win is chosen for script guis:
Now there's a smarter order, guis will use either:
- Scripts win
- Buttons win (if not a script from groups Wizards or Utils)
- Text win
- Closest bigger area
- Added a button to the scripts header so that it's faster to return to the buttons win (this can be made general), if that was the previous win used.
