[Feature Request] API Additions, The Sequel

[LeeThompson]

I'd like to see some additional API commands.

All of these can be performed using the web UI, this would merely add a way to add them for automation purposes.

createbackup - initiate a backup
domoviesearch (movieid) - would initiate a backlog search for movieid (or all if omitted)
doupdatemetadata (movieid) - would update metadata for movieid (or all if omitted)
doimdbsync - would initiate imdb sync
doupdatecheck - would initiate update check
dopopularmoviesync - would initiate popularmovie sync
dopostprocessingscan - would initiate postprocessing scan
dotraktsync - would initiate Trakt sync
domissingfilescan - would initiate missing file scan
