Transport properties client. #229
This branch moves support for exchanging transport properties from the sync layer to the client layer.
Local properties are stored in an unshared group. When a contact is added, the latest local properties are copied into a group shared with the contact. Whenever the local properties are updated, they're copied into the groups shared with all contacts.
The transport update messages include a unique device ID that prevents collisions between local and remote messages, and will be used in future for multi-device support.

This commit renames identicons to avatars in field names, and uses an ImageView
derivative to show the identicons, which should make implementing #214 easier.
Users were confused by the process of adding a contact for the first time.
This change adds additional explanation and a picture of what is going on.
It also moves part of the UI into XML files.
Closes#87
This will allow any activity to show the expiry warning and password
prompt, and to start and stop BriarService.
SplashScreenActivity, SetupActivity, ExpiryActivity and PasswordActivity
are special cases.
If the schema of the database is incompatible with the schema expected
by the code, the database throws a DbSchemaException. LifecycleManager
indicates the error to BriarService, which uses HomeScreenActivity to
show a notification and quit the app.
