Add 'spring-commands-rspec'

This gem allows RSpec to be used with the Spring preloader, eliminating
the Rails startup time when running tests. Was getting really annoyed at
the 10-second startup times every time I wanted to run any tests.

Here's a sample comparison running a single test file:

    Before:

    rspec spec/models/chouette/vehicle_journey_at_stops_day_offset_spec.rb
    Run options:
      include {:wip=>true}
      exclude {:js=>true, :meta=>true}

    All examples were filtered out; ignoring {:wip=>true}
    ...

    Finished in 2.01 seconds (files took 9.41 seconds to load)
    3 examples, 0 failures

    ---

    After:

    spring rspec spec/models/chouette/vehicle_journey_at_stops_day_offset_spec.rb
    Running via Spring preloader in process 45340
    Run options:
      include {:wip=>true}
      exclude {:js=>true, :meta=>true}

    All examples were filtered out; ignoring {:wip=>true}
    ...

    Finished in 2 seconds (files took 0.76843 seconds to load)
    3 examples, 0 failures

When doing TDD this is a huge workflow improvement.

Since the `/bin/` directory is ignored by .gitignore, you'll have to
generate the binstub manually to get this working:

    $ bundle exec spring binstub rspec
    $ git checkout bin/spring  # since this file is in the repo but is
    $                          # also in .gitignore so shouldn't be
    $                          # committed.
    $ bundle exec spring rspec  # enjoy!

To use with rspec.vim, add this to your Vim config:

    let g:rspec_command = "!bundle exec spring rspec {spec}"
