rename two rendering methods and performe some interface tricks about fullscreen

remove trailing spaces from end of line

Engine: * Rewrote stereo rendering * Simplified anaglyph rendering (no longer requires framebuffers) * Added stereo mode selection: Anaglyph (different combinations of red, green, blue and cyan), side-by-side (horizontal and vertical) and alternate frame rendering (AFR)

reverted stereo craziness - the experimental3D branch has been created for a reason

new quality slider widget (needs to be customized), removed obsolete arguments

merge

these were removed by mistake

Engine: * Added/merged support for anaglyph (red/cyan) rendering (might not be supported by very old cards; don't use it if you've got low fps anyway) Frontend: * Added a checkbox to options to enable anaglyph rendering

applying smaxx patch where it should be

Engine: * Engine will now try to load the grave "Statue" if it couldn't load a team's grave graphic (http://code.google.com/p/hedgewars/issues/detail?id=3) * Explosions may now create chunks/stones knocked out of the landscape (only supported on Olympic theme so far)

add some comments and fix indentation

New weapon graphics

creating a new branch for experimental 3d stereographic rendering currently it contains only an updated version of the anaglyph patch by Smaxx

I keep forgetting to merge.

Set these to saveSurf (still need to actually, oh, write the code to cache the textures)
