Bugfixes due to recent RNA renaming:

* Driver F-Curves were not getting fixed by the "FCurve/Driver Version
Fix" tool. This was causing problems such as shapekey drivers from
older (2.56 compatible rigs) failing to run. As well as renaming the
paths for these Driver F-Curves, the "disabled" flags also get cleared
from these drivers so that they can be run again

* "Revive Disabled F-Curves"  operator in Animation Editors can now be
used to revive disabled drivers too.
