 Adding temporal vector algebra (r58807) broke compilation on Windows and
 some Ubuntu machines. During start up it fails:

 I will move the tgis import to the places where it's actually needed, so
 it won't be imported when the gui starts. But still I am not sure about
 the other imports in temporal_vector_algebra.py. Can tgis be used without
 pygrass? Is pygrass needed for temporal vector algebra only? The imports
 should be more careful. Also it would be good to understand what's the
 problem with pygrass.Module v.overlay.
