Title: Spring support

Spring uses a command prefix together with automatically-spawned
background processes that close when you leave your terminal session,
negating the need for a separate, manually controlled server process like Zeus has.

The execution syntax is identical to that of zeus for guard-rspec's purposes (as far as I can tell).
