Rotating Skyboxes

The new skybox control system enables tilting the skybox in arbitrary directions and set its rotation on the three primary axes. For that, use the following console variables:

• sv_skyspeed
• sv_skyangle
• sv_skydir_x
• sv_skydir_y
• sv_skydir_z

All of those variables are stored in savegames and restored on load, which makes them easier to work with.
