D3D is a little more complete, lighting on models appears correct. Added rate scaling to the sound system. Not sure on the configuration yet, and its not queryable in any way. Misc sound related cleanups. git-svn-id: https://svn.code.sf.net/p/fteqw/code/branches/wip@3619 fc73d0e0-1445-4013-8a0c-d673dee63da5
