Big part of PhysFS support

* removed -mod argument
* removed -datadir argument
* removed -lang argument
* removed some dead ui code
* added resource manager and file loaders (stream and SDL)
* changed interface textures location to match new directory structure
* removed CGameData for mod support
* added PhysFS support
