Vega Strike Code

Sync to safemode branch -r12276, Fix referenced files in data so that they use relative paths from data dirs, minor fix to opcode so that Stdafx.h can be precompiled when/if that feature ever matures

Merging in svn head -r12275

Make Stdafx.h precompile-able ....just because it can, activateable when such proper changes are committed to automake

Make referenced files traverse root paths like normal files do

Fixed some shader errors, and made specmap a vec4 everywhere instead of casting it to a float and back.

Oops - those files weren't supposed to be there.

Quite some audio work ;D
Hope to get it fully working soon.
Only remaining tasks:
- Implement the simple SceneManager thread
- Implement the OpenALRenderer
- Implement the OpenALStreamer thread

Moving audio work to its own branch

new unit shaders (by chuck_starchaser); there will be a lot units, and systems to be reworked.

Updated accountserver to include possibility for redirection, warnings and errors as are supported in the engine.
