Title: OCIOFileTransform reload button, Python path fix

As discussed in #180, a reload button which increments hidden "version" knob

I did look at using the getCPUCacheID method, but append is called before validate, so it would be.. messier than the hidden knob!

Also fixed up an error with the Python installation path, which I broke with the changes in 80ac6839502a70a46733bc66e5c5a2e51df625a7 due to CMake variable scoping thing
