This patch makes the system map much better looking and easier to use.
0.846 change list:
- changed sprites on system map to animating models with effects (much prettier)
- now draw background of that system on the system map if it is loaded (if not draws current player level background)
- planets now show clouds and rings on the system map
- now unexplored part of the map (on system map and minimap) is a texture instead of a flat color
- added background on names on system/sector maps
- now effects handle scaling better
- changed black hole description to "usually don't have planets"
- made lines on sector map thinner
- fixed a filename issue in TextureCtx::load
- moved MapLevelMaxZoom to database instead of hardcoded
- turned off some shadow mapping stuff that was still doing stuff (doesn't seem to have any real fps impact though)
- fixed depth buffer clear between SORT_TYPE_TRANSPARENT_BACKGROUND and SORT_TYPE_OPAQUE_BACKGROUND2 to be more robust
