commit 5301d9a rework of previous commit: beta camera implementation

commit 276c124 beta version of camera implementation

-sky and skybox does not render

commit 9adb971 pass normals to dx9

-normals were being calculated, but only sent to GPU if the old ATI tesselation feature was used
-now I'm always sending them and this should improve lighting calculations in remix; this should not affect visually the standalone game

commit 5be780d allow nomipmaps setting for all textures

-added r_nomipmaps which ca be set to value "1"
-renamed r_ext_multisample to r_multisample
-allow GL_NONE as r_textureMode parameter
