@ashfurrow => Registration refactor, forgot PIN, help amendments

* New user creation can take a few seconds. So if you're placing a bid this process now happens inside the bidding view controller giving the user only one loading screen instead of two. 

* Added an API call for when you've lost your PIN, not done any UI around it.

* Talked with Kat, the button in the help file should take you to create a new user. I was surprised to not find it in the storyboard given that it's just static content. Might be worth porting over at some point to keep the app consistent.
