Add albumTitle, duration variables for use in Now Playing widget

From the configuration of “Now Playing Widget”:

Allowed variables: {album} {title} {artist} {duration} {paused} {playing} {pausedShowPlay} {playingShowPause}

(where this {album} variable is the album’s artwork image, rather than the album title).

I would like two new variables to be added, {albumTitle} and {duration}. Considering there are variables usable in other parts of the application underBTTNowPlayingInfoAlbum , BTTNowPlayingInfoDuration, I’m hoping these two fields shouldn’t be too difficult to add.

Ideally, there would also be a way to format this duration display to show like 3:04 rather than the raw 184 seconds value for duration.
