Watching for one of the spork instances

[Mange]

It would be awesome if guard-spork could support some way of restarting only the sporks that apply to a change. I propose the following syntax (if it's possible with Guard; I haven't checked):

watch('config/routes.rb')
watch(%r{^spec/support/}) { :rspec }
watch(%r{^features/support/}) { :cucumber }

Sounds good, feel free to submit a pull request.
