Start console OpenGL reincarnation

- Handle new command in game record and net - Inc protocol version due to changes

- New command 'set weapon' - Fixes bug with changing weapon while switching hedgehogs

Full support for out-of-source build

First steps to support out-of-source build

- Store sky color in theme cfg file - Repair water

Hopefully finish freebsd port

Try to prepare freebsd port for 0.9.2. Not finished yet.

Solve problem with crosshairs

Convert the rest of rotated sprites to be rotated by OpenGL

- Some optimizations - Rotate grenade sprite using glRotatef (much better result)

Add alpha-channel to maps

- Reanimate Volcano theme - Make clouds be transparent

Don't update all land texture when drawing tunnel (saves video throughput)

- Enable back console (doesn't render yet) - Make texture size be of power of 2

- Add alpha-channel to all sprites left - Reanimate ammo menu

- Save 8 MB of memory by freeing LandSurface and not using it anymore after game initialization - Reanimate girder (and partly teleportation tool)

Store Land surface in memory: - Fixes strange land texture disappering - Speed up operations, changing land after its initialization

Introduce UpdateLandTexture function to update just parts of surface

- Update land texture after explosions - Restore loading progress

Fix a bug introduced in previous revision (accidental delete of land surface)

Now game looks almost like it did before switching to OpenGL

Add alpha-channel to horizont sprites

More sprites are visible

Now hedgehogs are seen on map :)

Now land texture renders properly

Enable back fps counter

- Start conveting pngs to have alpha-channel

Enable water waves back

Respect alpha channel
