Updating build systems: folder release/bpydata/ moved to release/scripts/bpydata/

It seemed trivial enough, so I updated all systems (makefiles, xcode, scons, scons win installer), please complain if something went wrong.  Mostly it was just removing release/bpydata references, since the release/scripts dir is already worked on recursevely, handling dirs inside it.

For the scons nsi file writer script I had to write code for each new dir, but it can be recoded recursively, too (in fact joining all release stuff in a single dir tree with nothing else would be a good idea, making installation code simpler).  Since it's just python and I have a little more time now, I can help scons managers if they still need.

Thanks Campbell Barton for reporting.
