Long-click on a media attachment will now bring up the normal
context menu for a ConversationItem long-click, but with the
addition of a "save attachment" option.
This allows users to long-click on messages with media in them
and still see the other contextual menu options.

Fixes#926.
We have to do this, since with the new Storage Access Framework,
otherwise we can open the Uri only *once*. This would work well
unless someone saves a draft and goes back to the conversation -
then the Uri is opened again without the required permissions.

...for details.
1) In addition to the Recipient interface, there is now
RecipientDevice. A Recipient can have multiple corresponding
RecipientDevices. All addressing is done to a Recipient, but
crypto sessions and transport delivery are done to
RecipientDevice.
2) The Push transport handles the discovery and session setup
of additional Recipient devices.
3) Some internal rejiggering of Groups.
1) Move the attachment structures into the encrypted message body.
2) Encrypt attachments with symmetric keys transmitted in the
encryptd attachment pointer structure.
3) Correctly handle asynchronous decryption and categorization of
encrypted push messages.
TODO: Correct notification process and network/interruption
retries.
1) Move all the crypto classes from securesms.crypto.
2) Move all the crypto storage from securesms.database.keys
3) Replace the old imported BC code with spongycastle.
1) Make the radio change a synchronous action with a timeout.
2) Move the send logic into an MmsTransport, in preparation for
UniversalTransport composition.
3) Move the download logic into a synchronous receiver.
1) Added a new message status to MmsDatabase to
signify a pending MMS download which requires
APN settings.
2) Added a database method to query MMS messages
based on status.
3) Added login to SendReceiveService for processing
of MMS pending APN information.
4) Moved all APN/MMS settings into ApnPreferencesActivity
and transformed PromptApnActivity into a simple
informational activity.
5) Added logic to check for APN settings on send and
receive of all MMS (media, group, email) and direct
user to PromptApnActivity then ApnPreferencesActivity
if necessary.
6) Vocab/grammar adjustments.
1) Broke out the UI elements of the major Activites into stylable
attributes.
2) Created a 'light' and 'dark' theme for the newly stylable attrs.
3) Touched up some of the UI spacing.
4) Implemented dynamic theme switching support.
1) Fixed the "Unsupported Encoding!" problem.
2) Workaround for the Sprint issue, where the MMSC is adding a single
extra byte to the end of each encrypted message.
3) Fixed the "large blob of base64 text" on encrypted MMS problem.
