Message queues. #266
A message queue is a group shared by two devices that delivers messages from each device to the other in order. The first 64 bits of the message body contain a sequence number that's incremented for each message sent in a given direction. The incoming and outgoing sequence numbers and information about any messages received out of order and waiting to be delivered are stored in the group metadata.

When more than one invitation socket is opened, Alice should pick which one to use and Bob should use whichever one Alice picks. This fixes a race condition where each party picked a different socket and closed the other.
Helper class to reduce client boilerplate
* Renamed BdfReader methods for consistency with BdfList/BdfDictionary
* Added readList() and readDictionary() methods to BdfReader
* Added ClientHelper to reduce boilerplate when converting messages and metadata to and from BDF
* Moved PrivateGroupFactory to the same package as ClientHelper

Unit tests for ValidationManagerImpl
Unit test for the validation manager. I also changed the way the validation manager loads unvalidated messages - instead of using a single DB task to load all unvalidated messages, it loads a list of message IDs and then loads each message in a separate task. This prevents the DatabaseExecutor from being blocked by a long-running task if there are lots of messages to validate.

Add contact and transport keys in the same transaction
This avoids a potential problem where the app crashes after adding the contact but before adding the transport keys, leaving the contact unusable.

New polling logic for LAN. #252
Same approach as !104. Modified the poller to cancel any scheduled poll when pollNow() is called and randomise the next polling interval so plugins that call pollNow() at the same time don't end up polling in sync.
Depends on !104. Fixes#252.

New polling logic for Bluetooth. #251
Increase the polling interval exponentially each time polling is unsuccessful, up to a maximum of 60 minutes. The interval is reset to 2 minutes whenever a connection is made and whenever Bluetooth is re-enabled.
This should reduce battery usage when there are no contacts nearby.
Fixes#251.

The polling interval increases exponentially each time polling is unsuccessful, up to a maximum of 60 minutes. The interval is reset to 2 minutes whenever a connection is made and whenever Bluetooth is re-enabled.
Don't keep message status rows for groups that are invisible to the contact - this avoids the need to join the groupVisibilities table when selecting messages to offer or send. Add or remove status rows when group visibility changes.
