* master:
  Added note about set_arc_compatibility_flag to the CHANGELOG
  Looks like the -fobj-arc flag we added to OTHER_LD_FLAGS in ea918cd9 was an unsupported feature as it has now been removed from Xcode 4.3.2, causing lib tool to complain about an unrecognised flag.
  Instead of removing the VCR cache, namespace the cache by Ruby version.
  Remove Guard dependencies. Use `rake spec:kick` for auto-test-running.
  Make sure to use bundler for rake tasks that run bacon.
  Oops, use correct rake task.
  Move travis install commands to Rakefile and setup CFLAGS env for Travis/RVM.
  Hmm, chicken and egg problem on Travis, copy travis:setup task from Xcodeproj.
  Replace Xcodeproj git submodule by adding it to the Gemfile. Closes #172.
  Improve error report template. Closes #187.
