* From the error dialog you are able to back out of scanning or try again. Adds English localization for this message.
Adds an extra flag in OWSQRCodeScanningViewController to make sure that we don’t handle captureResults when capture is disabled (this was racing before because the call to [capture stop] is async and that was causing the cancel case to present the error dialog multiple times.
Fixes Signal-iOS#1347
* Fixes appearance of race with starting capture
Also marks the capture variable as atomic since it is accessed on
multiple threads.

Rather than verifying eachothers keys separately, you now verify the
privacy with your recipient by sharing a single composite number or
QRCode.
This is a breaking change, in coordination with Desktop and Android.
UX
--
Fingeprint is no longer in line with identity key error. Instead you
have the option of going to the full-screen safety number verification
experience.
Overhauled fingerprint design
-----------------------------
* use same modal dismiss button as elsewhere
* remove fingerprint from settings.
* quick slide in animation vs slow fade
* existing was painfully slow
* blur effect is better metaphor for something slide over top
* anyway there was a rendering glitch in the end of fade where
underlying navbar would "snap" out
Also Fixed
----------
Always provide a name string for contact
* Centralize all the nil-checking
* Fall back to "unknown contact"
allow multi-line error messages
// FREEBIE
* New bg (Bulgarian) localization!
* New sq (Albanian) localization!
* replace unfinished bg_BG localization with complete bg localization
* caps keys to make it easier to see missing localizations
* pull with newly pushed source keys
// FREEBIE
Also made identity key scanner appear faster. Previously we were
waiting for camera to initialize. Now we do this after the view has
loaded - with a black background, the affect is preferable than
lagging on the transition.
// FREEBIE
* Avoid intermittent crash in device manager via YapDatabaseModified
* Properly align refresh text when expecting new device
* Avoid glitchy activityIndicator while polling
* Expose edit mode toggle
Much of the code changes here were in the corresponding SSK update.
