[ux] Orbot design

[David Fifield]

With the talk about design guidelines I wanted to call attention to what
things look like in Orbot, the Tor distribution for Android. Whereas Tor
Browser has the hand-drawn-looking onion icon, Orbot uses a more
circular, abstract onion graphic in the same colors. It seems like they
must have put some thought into the design.
