Fixed typo in tpb and alternative_name in emit_series

This is my first pull request ever. I hope it works. I have implemented alternative_name handling in emit_series. 

Another solution that I toyed with is creating a new table "AlternativeNames", which has a many-to-one relationship with Series. Then the alternative names could be available for each show in SeriesTask obj. Or other variants of the same idea.

Right now I'm just fetching from series config.

I hope you like it and that it works (having problems running paver on windows)! At the very least I found a typo in urlrewrite_piratebay.

EDIT: ~~oops. Didn't mean to include my pushbullet changes. Guess I still have some stuff to learn about Git.~~ Fixed.
Let's put a reason on this, so it's a little clearer when it's out of context in the test failed message.
