BQP with QR codes
This MR implements BQP for key agreement over short-range transports. It also implements the Android UI for using BQP with QR codes.
Closes#117.
See merge request !84
@color/briar_text_primary is used in a lot of places other than the settings screen - if we want to use grey text in the settings screen we'll need to find another way.
Also fixed some misspelled resource names and included the colours from the Briar palette in color.xml.
Fix race condition when closing redundant Bluetooth sockets
The Bluetooth invitation code has a race condition: if Alice and Bob connect to each other at roughly the same time, they each consider their outgoing socket to be redundant and close it, resulting in both sockets being closed. This can be triggered pretty reliably by using two phones of the same model and pressing 'Continue' at the same time on both phones.
When more than one invitation socket is opened, Alice should pick which one to use and Bob should use whichever one Alice picks, which Bob can detect by trying to read from both sockets.
Hopefully the Bluetooth invitation code will be retired when #117 is merged, but I'm putting this up for review in case we need to keep Bluetooth as a fallback method.

Delete all app data when deleting account. #263
When deleting the user's account, delete everything in the app's persistent storage directory except the libs directory, which is populated with native libs when the app is installed.
Fixes#263.

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.
If two contacts publish their descriptors simultaneously, they may both stop polling without retrieving each other's descriptors. Continue polling for 2 intervals after publishing the descriptor.
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.
