Add i function.

Defaults a command to all subsequent command lines. Type "i git" and
all subsequent command lines will start with "git ".

Works with any number of arguments. ie. "i grunt build test --specs".

* Replaces "interactive git mode".
Limit torrents to main file only.
Return to command mode on Esc.
Add kimbus' shows and movies.
Use emit_series with trakt_lists.

This allows the trakt api to be hit just once in order to grab the list
of shows. It also prevents the task from being flooded by a new show
added to a watchlist, and allows for better back-filling of un-
downloaded episodes.
Better pushbullet notifications.
Reduce torrent seeds requirement.
[touchup] Remove priorities.
Backfill new shows.
