Add PhotoPrism (#15)

* Add initial configuration for PhotoPrism. Has not been tested yet, but options have been analyzed and tweaked.

* Begin testing. Fixes. Running pretty well, seems neat! Need to figure out user management other than admin.

* Add output to source so that we know it worked.

* Modify comments to explain a use free-to-win use case.

* Go ahead and give the full path on the success path.
