Bugfix #19663: Renaming named data doesn't fix F-Curves
RNA Paths used in F-Curve, Drivers, etc. now get renamed when some data that they use gets renamed. This only works when things like Bones, Constraints, Shape Keys, and Modifiers get renamed, but other cases can get added easily.
The code here only performs simple string replacements, so there is the potential for problems when several sets of data with the same names are present. For example, if there are multiple armatures with bones that have the same names, renaming a bone on one armature (with a bone on another armature having the same name) will break all the drivers on the other one, even though they aren't really connected. However, I don't expect the aforementioned scenario to really be a problem in most production scenarios.
