Draft: FE-935 New search UI
This branch satisfies the new search screen tabs, placeholder text, and general UI. Doesn't not include new functionality (seeing connections and requests as search results)
This is a major refactor of the previous search code.
Search screen is now a parent fragment (UserSearchFragment) that hosts the tab fragments (each a FactSearchFragment subclass) in a ViewPager. UserSearchViewModel controls the logic for the parent fragment and the child fragment tabs.
