Do not display baseq2 savegames in mods / addons

Browse source 
The savegame list is generated by calling FS_FOpenFile() for each
possible savegame name. When a file handle is returned the savegame
exists, otherwise the savegame slot is empty. But FS_FOpenFile()
searches in every directory known to the VFS. If a savegame file
isn't found in $moddir but in baseq2, the file in baseq2 is opened
and a baseq2 savegame is displayed in the mods / addons savegame menu.

The fix is compromise between a clean solution and invasiveness:

- Refactor FS_FOpenFile() to include FS_FOpenFileRead(). FS_FOpenFile()
  was used only to open read only files, limit its's possibilities to
  do exactly that.
- Introduce a new flag "gamedir_only" to FS_FOpenFile(). When true
  only the gamedir directories are searched and not other directories
  like baseq2.
- Change all callers to FS_FOpenFile()s new signature.
- Use the new gamedir_only flag to limit the searchpath for savegames
  to the gamedir.
