Updated to latest AS

Since we're targeting API >= 15 the appcompat support library isn't needed. I've dropped this library requirement and have migrated the themes over to properly use the dark Holo one, with some customized action bar coloring. Things look a lot better since now we can have proper holo dark style text and spinners put in for us by the theme.
Putting in proper load failure checks/handling for loading the index

We now will respond properly in the case of logging in with an invalid cookie for example.
Thinking about a new layout for the torrent/user/request searches

Instead of having the search boxes be in the list header and thus be scrolled away from as we browse we'd put them in a fixed view above the list that will collapse when we scroll past. Clicking this will then open up the search boxes so we can run a new search without needing to scroll all the way back up. This isn't implemented yet but I'd like to try it out after the forums are in and I start doing more polish work.
LoginTask will now also check the status of loading the index
Can now actually vote on and view poll results

Changing to the result view after voting on a poll being viewed is still in progress. Instead of re-loading the entire page we'll simply update the poll on our side and show these new results. Also need to make it so the dialog changes to the results view instead of going away after clicking vote/show results.
