New in this version
* Search! The top-right button now opens a menu with a few options, one of them being search. It currently works just the same as search in the web interface.
* Username autocomplete. When you type an @ on the posting screen, the app will now auto-suggest users for you to address.
* Deleting toots now works.
* Links to toots and users pasted in toots are now opened in Toot instead of opening in the web interface.
