Summary:
We now have a `MessageItemContainer` class that handles the logic of
deciding what kind of message to show. We introduce a new `PendingMessage`
(which is just a sublcass of `MessageItem`) that has the spinner and
stuff.

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.
React-dnd is a nice library but it assumes it's going to be the only thing managing your drag and drop in the entire app. It also hides the underlying dataTransfer object so it's difficult to implement native drag and drop behaviors other than for Files and Urls, which they special-case.
Implementing it manually really isn't hard, and we can do things like attach a text/plain version of contact data to the contact drag.
