Improve 3D functionality

This PR contains everything I needed to download 3D BR-Disks. The changes include:
- Using release size to determine quality as many BR-Disk releases do not have any tags in the release name
- Added a 3D tag in the renamer
- Added 3D to adding releases from the renamer.after event
- Added spotnet password searching in the release description as most 3D BR-Disk are password protected
- Updated all renamer tag caps to be as the standards (e.g. dts -> DTS) ref WikiPedia
- Some small fixes

This PR is not ready for pulling yet! In the end I will rearrange to commits to group the changes more logically :)
