[Feature request] Option to run specs by name, not line number

[AndrewRayCode]

Rspec lets you run tests with rpec test/spec.rb -e 'name of test' where name of test is some subset of the test string. This can be very useful for when you're refactoring tests, and the line number moves around. Is this something you think would work in this project? I might try exploring a pull request if you approve it @noku
