Here's whatsnew for this Odyssey 2 & Videopac+ emulator:

- added the option -biosdir to define bios directory path

- directory search fix : When you don't have the "roms/" and/or "bios/"
directory, the program will dump core (by Walter de Jong).
- O2Launcher works now, o2em ignore roms and bios path if o2Launcher
is running.
- quad display fix: changed the way quad chars are drawn, fixes problems
in KTAA as well as score display in Black Hole and Red Baron (Soeren Gust)
- support for Soerens MegaCART bank switching (Information about
how to use this will be included in the next verison of Soerens
Bios-Documentation) (Soeren Gust)
- new feature in debugger: savevpp to make an uncompressed dump of the VPP
screen and slide data (Soeren Gust)
- dis48: fix to work under linux again (Soeren Gust)
