minitest-autotest 1.2.0

autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead.
