bugfix for [32368] Added controllers don't count over 10
Blender original code (NaN likely) was relying on strcmp to sort the list of controllers.
As it happens, in strcmp 10 < 2, thus the list was never in the right order.

The curious thing is that in 2.49 it worked, but I think it did because the make_unique_prop_names function was called twice. Strange ;)
The solution is to use blender BLI_natstrcmp to do natural sorting
