Update project file to be universal app

- Still issues around archetecture type
checkpoint remove all but armv7
Build for active architecture in debug mode

- Rebased against master; allow all three
  architecture + simulator for targets
  so we can build against all supported
  devices. arm64 will probably not work until
  redpark lib with arm64 slice is added in a
  seperate branch. Tested against iPad mini
  and iPhone 5.
Merge branch 'basic-iphone-support'
