* 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.

Conflicts:

causing lib tool to complain about an unrecognised flag.

I considered removing this entirely but have decided to keep it around 
as an option for the time being. You can get the previous behaviour by
adding set_arc_compatibility_flag! to your Podfile.

I'd like to get rid of this entirely eventually. Re-closes #142 unless
anybody has any objections.

See d3bd2989.

This also fixes a failure on Travis.

Apperantly OS X's BSD tar accepts the x option even if the archive is not a gzip archive.

I run pod search not from directory with xcode project and it there was
an error with reading podfile. Than I added check for existence of
podfile. [#177]

to prevent broken syntax highlighting in emacs (and maybe in another
editors too)
