Upgrade mobile UX to Oasis 0.9.0

Rebase onto upstream 0.9.0. Mobile topbar (logo->home, avatar->profile),
hexagon category nav (hive) and bottom bar; remove the six top-bar
buttons (inbox/pm/publish/search/graphos/peers) that cluttered the header.
Theme OasisMobileUX carries topbar/hexagon/bottombar styles.
