[Bf-committers] Blender Startup Time

Some more tests and found lazy loading of modules in other areas,
gives good speedup on cold start.

Times don't compare to last tests because I disabled some options
(BGE, FFMPEG etc).
I did lazy importing of modules:
  traceback, shutil, time, math and pydoc
  I also removed 'collections' import as well as netrender. *

Results for "time ./blender -b" after flushing disk cache,
Normal: 8.923 sec
Lazy Loading: 4.647s

* note, removing collections import means we would need to use a
different ordered dict metaclass, I'm not worried about this since we
don't use many of the OrderedDict features, we could have a cut down
