More descriptive Rockon Catalog

[seffyroff]

Right now browsing the Catalog of Rockons is very sparse. I don't know the source of the Rockon (whose Plex comtainer is that) without looking in Github at the contents of the .json. I don't know the version number, or last update version - these are important :)

@seffyroff Sorry to wake this sleeping issue up but it's a really good point.
