Add a cvar fs_portable. When set to 1 the game is 'portable'.

Browse source 
Normally Q2 writes all persistent data (the configurations, saves, etc.)
into a subdirectory in the users $HOME. That can be a problem when the
game is installed onto an thumb drive or something like that. Therefor
provide a cvar fs_portable. When set to 1 the games uses it binary dir
as it's persistent storage location.

Examples:

./quake2 +set fs_portable 1
./quake2 +set basedir ~/games/quake2 +set fs_portable 1

fs_portable is _not_ saved into the config file. It must be set at
every start!

This closed issue #158.
