Removed deprecated popup code.

Extension no longer displays a popup, instead r/friendsafari/new is
loaded and filtered by what the user has specified in the options page.
Added options page. Not yet hooked up.

Options page allows you to add or remove pokemon and types to track.
This isn't hooked into the actual badge logic yet.
Both filter and update now connect with options. Fixes #1

Both the /new filter and the notifier will now use the Pokemon and types
set in the options. This data is stored in chrome sync.
