Merge lp:~trb143/openlp/media_state into lp:openlp

[Tim Bentley]

This is to do a code review and see what mess is left

Refactor Media and add State management. (there is more to do!)

* Add Start of State management with dependency understanding. (works for VLC and PyMediaInfo)!
* refactor plugin manager to use this (part 1)
* move loading of static stuff from mainwindow.
* Only use VLC for media, remove other options (more cleanups to be done later)
* clean up pymediainfo usage
* remove audio and convert to vlc for song audio player
* fix many bugs discovered on my travels.
* upgraded vlc.py

Only got to line 1023, will take another look later, just a few minor issues with doc strings (see inline comments)

[Phill (phill-ridout)]

I assume the commented out code is a work in progress?

L7027: if statement not needed
L7953: I'm not convinced the user will want to see a dialog box every time the preview, go live, or edit a song that has audio....

Also it looks like you've removed the background audio controls from the live slide controller, but not replaced them with anything?

review: Needs Information

[Phill (phill-ridout)]

L7953: I'm not convinced the user will want to see a dialog box every time the preview, go live, or edit a song that has audio....

Could you comment this out for no, I'mo concerned that this would too easily be overlooked. (Its only going to happen for people who try to load a song with background audio and have the media tab disable / problems with VLC integration.

If you can do that and resub, I'll be happy to approve it!
