vector * quaternion: Simplified by precalculating the repeated products and removing math.fsum.
quaternion * quaternion: Add more F32's to get a result closer to SL's (still not there, but we're definitively closer now).
We left out quaternion/quaternion in the tests, and the q*q test was not general enough (had many zeros). Remedied that.
This test suite has been in use for a long time now, in place of the obsolete and unmanageable testparser.py and testfuncs.py. It verifies the complete optimizer output to stdout and stderr, to ensure that the output matches the expectations.
See unit_tests/README.txt for more info.
