Vega Strike Code

Added debug config file option, takes arguments 0,1,2,3 with 0 turning verbose debug off and 3 being most verbose

Add verbose debug config option to config file and allow command line --debug to override it when running vegastrike. Takes same arguments as command-line

Revert non-nv-cubemap change to gfx toggle texture call so it compiles

sync with safemode branch -r12607, added --debug argument and new debug output function, see forum or code change for info ...or --help

merge with trunk -r12605

Add --debug argument to vegastrike, takes priority arguments =1 or =2 or =3 with 3 being the most verbose, see forum post or code for more info

Ok, fixed most of NV_CUBE_MAP issues.
Remains: flipping all "back" background textures along the 45 deg axis.
That is, flip both x and y on all _back textures, to make dds unified cubemaps compatible with 6-file ones.

NOTE: do not comment debugging output, which is useful.
Rather, a proper debugging API should be placed somewhere and all logging should be done with that API, each log message should have a level (debug, info, warning, error), and a config setting should define the desired logging level.

renaming all five bubble_xxx.png textures to bubble_xxx.texture; and replacing bubble_norm.texture with an improved version, now DXT5-compressed (the rest are uncompressed png's).

adding a new bubble_norm.png and blender node network files used for its production, and a readme for the method used.
