Spring support

[vosechu]

This is a placeholder as I work through figuring out how to add Spring support to rspec-autotest. If anyone has already figured it out though I'd love some advice.

Best I can find is to override the rspec command, but it's a garish hack. Is there a better way? Or is direnv the only good way to do this?

require 'autotest/restart'
require 'autotest/bundler'
require 'autotest/rails_rspec'

Autotest.add_hook :initialize do |at|
  # Allow rspec to use Spring
  RSpec::Core.instance_variable_set(:@path_to_executable, File.expand_path('../bin/rspec', __FILE__))
end

I've never used autotest or spring so I can't really speak to the best way to use autotest, spring and rspec together. Changing path_to_executable is definitely a hack that would be good to avoid. Rather than changing what RSpec considers the path to its executable, couldn't rspec-autotest provide a way to override what rspec executable it uses?

@myronmarston: No worries about not using autotest, we just wanted your opinion about whether there was a facility in RSpec that would allow us to change this dynamically. But I think we can do it on the autotest side.

I think we could fix that part of autotest. @seuros, do you think it would be reasonable to check for the existence of bin/rspec? Or is that too rails and spring specific?

I'm looking at a quick little conditional around https://github.com/rspec/rspec-autotest/blob/master/lib/rspec/autotest.rb#L45
