Add release.update event

Proof of concept commit.

It updates the database and calls movie.update.id to refresh the entire movie in the frontend. It would be better to crease a static js file in the release folder and add release functionality there including updating one release only.
clean-up searcher
frontend release.update
Add missing status
Update movie quality status colour and text

It isnt perfect this way. I think we need to add a sepperate function to
do this and call that from both when CPS is loading the page and when it
updates a release (e.g. just rebuild the icons)
Remove movie_dict
Set missing to ignored after 1 week
fix colour order
Merge branch 'develop_release' of git://github.com/mano3m/CouchPotatoServer into mano3m-develop_release
Rename release.update to update_status
Merge branch 'refs/heads/mano3m-develop_release' into develop
