1) No more blue/green for outgoing messages. Just lock or no lock.
2) Use 9-patches instead of shapes for better bubble performance.
3) Use tinting rather than different colored assets.
4) Change outgoing status indicators so that they don't change
width of the bubble as they update.
5) Switch to using ..., check, double-check for pending, sent,
delivered rather than using bubble tone to indicate pending.
