BPython:

-- applied patch by Michael Reimpell that lets scripts registration info be either commented out or not (commented, it doesn't interfere with Python documentation tools.  The patch also fixes potential overflows, thanks (and sorry for the confusion) again, Michael.
-- fixed NMesh_hasFaceUV, it was returning true for false and vice-versa.  Reported by Jonas Petersen with patch, thanks.
-- added 'homedir' and 'uscriptsdir' to Blender.Get() to get Blender's home dir and the user defined scripts dir.
-- related to the above doc updates.
