Fix for radians-degrees version patch, more testing should have gone
into this before committing:

* Subversion was not increased, meaning that conversion would be applied
even on files saved with the new version.
* Drivers were not converted.
* FCurve generator modifiers were not converted.

This seems to cover all cases we found for Durian, if another conversion
is needed for this, be sure to increase the subversion number and do it
in a separate if() test, otherwise files will break.
