qfusion r10

This is pretty much post Warsow-0.4 release that includes the renderer updates you might have already seen there. However, I've decided to make another release from the old source tree just in case anyone cares ;)

Here's the short changelog:

- Added shadow maps support for models

- Added support for simple distortion effects along with Fresnel effect to shaders

- Added occlusion queries support for shadow maps, portals and models

- Added outlines GLSL shader for cell shading effect

- Added decal stage to "material" shader passes

- Bugfixes and optimizations

Love q3m4 with outlines :)
