Fix Watchlisting

[lhl]

See: https://github.com/upcoming/upcoming-www/blob/master/controllers/watchlists.js#L11-L15

• How should watches be created
• Making sure it lists/get the status
• Don't create dupes
• Toggle properly

OK, here's what I did:

• watchlist items are stored in DB properly (w/ created_at and not duping)
• Adding and removing are now progressive (XHR w/ jQuery)
• Status is updated via AJAX for now (status set to either "attend" or "remove")
• Remove deletes the watchlist item; may want to consider logging that stuff somewhere for future data

TODO:

• Modify the event jade view stuff so that the static HTML reflects watchlist status properly

Watchlist nomenclature is a mess - the Watchlist model services a Watchlist (list of events) and also creates/modifies individual items... no me gusta, should have a standard naming/pattern since we have event and event lists as well, not going to deal w/ that, but making a note.
