* Visual tune-up

* Move the feed selector to the footer

* Fix to 'new posts' poll

* Add the view header as a feed item

* Use the native driver on the tabbar indicator to improve perf

* Reduce home polling to the currently active page; also reuse some code

* Add soft reset on tap selected in tab bar

* Remove explicit 'onboarding' flow

* Choose good stuff based on service

* Add foaf-based follow discovery

* Fall back to who to follow

* Fix backgrounds
