[Wine] multiple wine versions

[Gert van den Berg]

The PREFIX option when you compile Wine determines where it installs.
(It should default to /usr/local)

When running Wine, you want to set the WINEPREFIX environment variable
(It is a run-time option, not compile time) (Yu can export it to set
it for all processes started from that shell, or you can use env /
prefix it to the command to set it for every involkation)

e.g. WINEPREFIX=~/.wine wine winecfg # Gets primary wineprefix's winecfg
WINEPREFIX=~/.wine-cssource ~/.wine-1.3.6/bin/wine winecfg # Gets
~/.wine-cssource's winecfg using Wine binary from the compile wine
1.3.6 (reinstalling it into /usr/local might make more sense...)
