Contributions, shaders, new normal maps

Polishing, polishing, polishing - that's what's being done right now. And nice contributions by our new community member getter77, an aspiring and talented game developer. Right now he has created a pair of male voicepacks (1 for psychotic and 1 for bully personality). Thanks getter77 (aka Brian)!

Meanwhile I've fired up gimp-normalmap + gimp-dds plugin again on my laptop, and started to spit out a dozen of normal/height/spec maps for the already present building/road/tree textures. The result is awesome. The heavy use of such mappings culminated a series of interesting bugs/detection of missing features of the shaders. Most of these problems are now resolved, also a new level of normal map shader detail is added to the Options menu (detailed shader can handle 2 lights blended). Also fog is now supported by those shaders - and the shadow render pass is also fixed to work correctly with those. Check the screenshots for shaders/mappings in action! :) On the second one you can catch tidbit's new stone base square for the anatipion towns. Release is very near now...
