0.9 build 36 (alpha)

Changes in build 36

1. Added top menus in profiles and community fragments.
2. When scrolling the feed, the resolution of the placed placeholder no longer loses its properties to make scrolling less jerky.
3. Refactoring switching between fragments, also to the FragmentNavigator class.
4. The name of the profile or group no longer disappears when hiding the title through scrolling.
