Subject: get rid of FS_DefaultExtension, add FS_SetExtension which may set if missing, or... 
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=6eb212d8bfeb77e4376806e62bc54039db5b8ffc;p=xonotic%2Fdarkplaces.git

get rid of FS_DefaultExtension, add FS_SetExtension which may set if missing, or always override, the extension depending on parameter. For now, override in all cases.
