This reduced our image size by 92%. It saves us 4MB.
Several of our images had several hundred KB of plain text Adobe metadata
crap. Some had full blow Fireworks editing histories embedded in them.
I re-saved out these images and verified on both a diffing program and by
comparing the app that no pixels changed in the compression.
Summary: Adding star button to message-toolbar view
Test Plan: Added spec for starring message from the message-toolbar view
