What's new/fixed:
- Packsunpacks 5455 and 5558 debug (intended for BFM use only). Kludge note: the 2bl is patched when the BIOS is patched. (Thanks koitsu, myria, ed/gimli, Phoenix, nghtshd, et al.)
- New config key so old configs will need to be updated/replaced.
- Added some config info to log file output.
- Logfiles go to stderr if the logfile can't be opened.
- Added some info to the boot flag patching dialog (BTW, thanks to Iriez for the idea to make boot flag patching optional).
- Fixed crash when loading the current bios preset with no BIOS loaded.
- Fixed logfile typo.
