I don't care but Android Studio complains.

This was meant to prevent key reuse with BTPv1, it's no longer needed with BTPv2.

Removed consumers from BdfWriter. #234

Cleaning up some unused code.

Navigation drawer (squashed and rebased).

This is @ernir's work on #30 and #181, rebased onto master with recent changes to ConversationActivity and ForumListActivity ported to the respective fragments.

Show Bluetooth address from Settings.Secure in TestingActivity

* To help with investigating #225 (and maybe other bugs in future), show the Bluetooth address from Settings.Secure as well as the address from BluetoothAdapter.getAddress()
* Add Settings.Secure.ANDROID_ID to the entropy pool - it may provide up to 64 bits of extra entropy from the perspective of a remote attacker (no extra bits from the perspective of a local attacker in the same user account, who sees the same ANDROID_ID)

Replaced broken jsocks jar. #228

Fixes #228 and may also fix #217. @str4d and @grote, please test and confirm.

Update contact list when contacts are deleted. #227

The logic in ConversationActivity for adding or updating items didn't allow for items being removed. We *could* come up with logic for doing that - throw all the items from the adapter into a set, remove any items corresponding to current contacts from the set, then batch update the adapter to remove any items remaining in the set - but I think it would be overly complex. It's simpler to just clear the adapter and add the current contacts.

Also tidied up some adapter code while looking for the bug.

Don't disable Bluetooth unless we enabled it. #226

Also removed unnecessary adapter notifications in various places.

Run hooks when contacts/identities are added/removed. #209

Now that the sync layer is separated from its clients, actions that used to occur within the DatabaseComponent, such as adding or removing private groups when adding or removing a contact, have to be handled by clients.

This patch adds a mechanism for clients to register hooks with the Contact/IdentityManager to be run when contacts/identities are being added/removed. The MessagingManager uses ContactManager hooks for adding and removing private groups, and the ContactManager uses IdentityManager hooks for removing contacts when an identity is removed.

I've also changed the way some components register with the LifecycleManager and EventBus.

This merge request depends on !64 - I'll merge them at the same time. Closes #209.

Whether or not a class needs to run as a service is an implementation decision.

Separate the sync layer from its clients. #112

This patch contains most of the work for #112. MessagingManager and ForumManager have been converted to BSP clients, and the sync layer's message and group formats no longer contain any client-specific data.

Each client has a MessageValidator that's called by the ValidationManager to validate messages belonging to the client. A new MessageValidatedEvent informs listeners when a message has been validated. This required some changes to the UI, especially the notification manager.

While working on the notification manager I realised it was calling Android API methods from background threads, which may be unsafe, and the notification logic was split across BriarService and AndroidNotificationManagerImpl. So I refactored those classes, along with AndroidExecutorImpl, which was using an unnecessary background thread.

Still to do:
* Synchronise blocks, not messages
* Add message type field to message header as per BSP spec
* Convert TransportPropertyManager into a BSP client
* Convert SubscriptionUpdates/Acks into forum client messages

ENH: Replaces transport config with namespaced settings

This MR contains the following:

* Adds a new guice module: SettingsManager, that abstracts the settings interface from the underlying database
* Uses SettingsManager to replace the db.getConfig/mergeConfig calls in the Settings activity
* Replaces the getSettings and mergeSettings calls in the database modules to include a namespace parameter. Updates the corresponding queries in the Jdbc module
* Removes the TransportConfig module, as it is not used anymore
* Updates the DuplexPlugin interface, to reflect this change in schemas and calls
* Updates the calls in the corresponding plugins, for both briar-android and briar-desktop
* Updates the hardcoded plugins in the tests to reflect these changes and updates the unit tests.

Offer option to uninstall Briar in a panic event (#211)

Due to the nature of how Android app uninstall works without root access, this requires manual confirmation after a panic event was triggered.
