First construct a null message of random size and contents and send it to the
destination. Then include that same padding in the verification sync.
Note that the sync message is additionally randomly padded like all other sync
messages.
This lets Verified sync messages appear the same as normal sync message traffic.

Just log em for debugging. Also update the error messge thrown when we get a
content message with no supported properties. It may be empty or may just have
an unrecognized field.

Sessions established with the previous identity should no longer be used for
sending, so we should close them.
Since we've added this call to saveIdentity, we can omit the call to it after
profile fetches.

processVerifiedMessage checks the current state of the database against the
identity key from an incoming verification sync message to determine whether or
how to update our local record.
When syncing a DEFAULT status and we have no local record, it's a no-op, but
we'll log it.
When syncing a DEFAULT status and we have non-default record with the same key,
mark it as default.
When syncing a VERIFIED status and either:
1. we have no key on record,
2. we have have a different key on record, or
3. we have the same key on record, but not verified
mark it as verified.
Otherwise do nothing.

Ensure processVerified resolves
The shield matches the Android app's key change notification, and the
clock icon was easy to do and makes it easier to visually distinguish
those items in the conversation history.

This adds a new method to message sender for sending verification sync messages
and a new event to message receiver representing incoming verification sync
messages. Currently the event handler just logs the message.
// FREEBIE
We also show more errors than we used to in the MessageDetail screen
to help make it clear what is happening, and why the user would need to
re-send.

A good bit of CSS was required to keep the text color changing along
with the text it is nestled within.
Also: took this opportunity to increase the contrast of the number and
verified section right under the contact name in the group members view.
