netPhotoGraphics version 2.0.01

[stephenbillard]

This is a maintenance update to the 2.0.0 release.
Some folders have been renamed (e.g. zp-data is now npgData) and infrastructure has been put in place for other similar changes.

Of course, there are the usual bug fixes and security improvements. The detailed list of changes may be found at https://github.com/ZenPhoto20/netPhotoG ... its/master
