* Ensure all controls visible at all times, on all form factors, even with keyboard active.
* Improve focus (i.e. auto-focus textfield on arrival and after errors).
* Move to programmatic view creation and layout.
* Improve spacing and sizing.
* Replace “change number” button with “back” button.
* Submit code with return key.

* show better errors if it *does* happen.
If someone tries to send from their old device, they'll see a
depressing, but sensible warning message.
* new translations

* Separate registering an account from registering for push notifications
* Allows us to complete registration without prompting user for
notification settings.
UX Changes
----------
* Automatically keep push tokens in sync on startup.
Push tokens *can* change, though they rarely do. It happens more often
for people switching between appstore/beta builds.
fixes#1174
* Show alert with registration failure
* add secret 8-tap debug log gesture to registration flow
* Move registration to separate flow
* don't see flash of inbox when first launching
* show useful error messages when given wrong code / no code
* remove background fetch
We werent using it, but only relying on a side effect of it which is
no longer necessary.
Code Changes
------------
* More registration logging.
* Install PromiseKit with carthage
Our dependencies are not yet framework compatible, so we can't use
cocoapods.
* Merge preferences util "category" into superclass.
The immediate reason for this is Swift interop was assuming optional
types were not optional, and exploding when a value was nil.
This is clearer anyway, since we were treating it like a subclass, and
it was the only thing using the class anyway.
* auto-genstrings now searches *.swift (and *.h, which was previously
broken) for translateable strings.
