BIG change in directory handling:

- Unix users can "make install" and "make uninstall" (as root).
- Installation creates shortcuts "grafx2" and "gfx2cfg" in /usr/local/bin
- Installation puts data files (icon GIFs, gfx2.dat,..) and the actual binaries in /usr/local/share/grafx2
- At runtime, the programs search and create configuration files (gfx2.cfg and gfx2.ini) in ~/.grafx2
(But if there are some present in program's own directory, they override)
- Uninstall removes programs and data, but leaves all users' configurations.

Win32: User's config directory is %APPDATA%\GrafX2
Win98: %APPDATA% is not set by default, so the program falls back to executable's directory.

Tested on Debian Linux
Partially tested on Win XP (early version)
Tested on Win98
