Added most basic use of FragmentTabHost to introduce a 'Mentions' tab.
Reintroduced path for inserting newly posted tweet.
Added the basic stuff needed for a profile view. With lots still to do.
Correct paths now lead to the profile page, supplying a User, and that user's tweets are loaded. But the fragment appears to be incorrectly sized and the other fields aren't populated.
Added appropriate fields to User, and their display within the profile activity.
Tweaked padding, hopfully very slightly to improve this view.
Added a listener protocol to the statuses fragment, implemented it in a new common parent to the profile and timeline/mention activities so as to display a progress spinner.
Set loaders to default invisible.
Added newly completed tasks.
Ensured the progress bar doesn't just show perpetually if there's less than a screen of information (by ensuring that accesses don't continue non-stop). Also fixed activity titles and in-app appearance of the white icon.
Updated readme.
