Fixed quote_update view from not rendering.

Had to unpack the pk of the episode into the tuple that the widget expects.
I don't like the solution, but kluging it in place of time.

Also put some duct tape on another bug that would fail to render the view
if time_quote_ends was blank.

Resolve #74
Merge branch 'master' of github.com:podcastquotes/podcastquotes
