Project: Add DevelopmentTeam configuration (google#157)

This is a generated xcconfig in the Rakefile which gets included by the project
to set the DEVELOPMENT_TEAM key to keep Xcode 8 happy. The development team is
figured based on the available “Mac Developer” certificate.

Also update the way SantaCache declares a ‘zero’ value, update the
OCMock pod and add a few missing includes.
