XBMC Media Manager (Frodo only)

This is my attempt at a media manager for the XBMC database. It uses the new json methods in XBMC to change the database entries.

Some features of the 'manager' are:
editing of movie, tv and episode information and images (music will be added at a later date)
accessing information from TMDB, TVDB and fanart.tv to get new or up to date information and or images.
exporting the library using XBMC's built in database exporter.

A picture is worth a thousand words, so here is a less than average quality video of it in action

There is still a bit of error handling and logging to be added, but it "should" be fully functional and ready for testing to iron out any bugs that may be in there.

The UI side of things could do with a little work too, that stuff is my achilles heel..

I havent done any testing on any unix systems yet. I wanted to get this together as a PR so it can undergo some testing on other systems.

It requires a frodo build from 8th August onwards

EDIT: forgot to mention that all images get cached in the datadir/cache folder to help with the load on tvdb/tmdb/fanart.tv
