- fixed: fog density calculation for fixed function was not correct.

shader rework
...
All those special shaders have been merged together.
Mostly working but the non-shader lighting seems a bit broken.

Do not use the shader to handle STYLEF_RedIsAlpha.
...
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...
This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

- removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
...
- removed cm parameter from many functions.

- remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use.
...
- use the cleaned up decal lighting code from the first GLEW branch.

- changed handling of DynLight in shader to serve as a global dynamic light color for all lighting modes.

- added objectcolor uniform. This will be used to hold the thingcolor for shader based rendering.

- rewrote vertex buffer code to require GL_ARB_BUFFER_STORAGE extension.
...
This means it won't work anymore on anything that doesn't support OpenGL 4.0, but I don't think this is a problem. On older NVidia cards performance gains could not be seen and on older AMDs using the vertex buffer was even worse as long as it got mixed with immediate mode rendering.

- changed rendering of glowing walls so that it doesn't require an additional vertex attribute, just pass the floor and ceiling planes as uniforms.
