Blender Git Loki

SCons updates
* Added the options to build (configurable via config.opts):
- blender dynamic (default enabled),
- blender static (default disabled). Not working because of a linking order
problem. The /usr/lib/libGL.a and /usr/lib/libGLU.a flags need to be
appended at the end of the link command, not directly after the linker.
Mailed the SCons mail list for a possible solution.
- blender player (default disabled). Not implemented yet anyway.
- blender plugin (default disabled). Not implemented yet anyway.
* Added the following variables to the config.opts:
- OPENGL_STATIC. This flag is only needed when building blender static.
- USE_BUILDINFO (true/false). Display build information in the splash
screen. When enabled, it will always rebuild source/creator/buildinfo.c,
so for compilation speed reasons, it is not adviced to enable this all the
time.

I had to make some adjustments specifically for the windows build
(winblender.res) file. This file is only compiled when building the dynamic
blender. I hope this is correct.
