Latest updates

This PR is all my latest work:

I wont be using XBMC Github after this any more only my personal repo. But feel free to make any comments and I will improve it. Sorry the commit history is screwed up again :/

- New categories
- All indentation and quotes should be fixed and standardised
- Disabled review button and removed the feature. Nothing I can do with this until we have a way to access usernames from forum
- Removed the old multiple sync pages and moved into the install folder
- I've given up trying to manually upgrade the database, it was getting far too complicated so I've just supplied the latest SQL file
