Refactoring the search path magic, step 3: Remove now used code.

Browse source 
Remove all functions that are no longer used:

* FS_AddGameDirectory()
* FS_SetGameDir()
* FS_AddHomeAsGameDirectory()
* FS_AddBinaryDirAsGameDirectory()

While at it try remove as much global variables from filesystem.c as
possible. Also fix a small, longstandig bug: The download code should
treat .zip and .pk3 files as pak files and not as normal directories.
