Audited headers for nullability

Added some nullability qualifiers in method implementation selectors for consistency with declarations.

The user dot view now has a non-zero size. Previously only its layer was sized properly. Also resolved some pedantic warnings about missing designated initializer overrides.

Xcode 6.3 or above is now required for building this project.
