Minitest Runner Command
MiniTest needs a commandline tool for running tests, just as TestUnit had with testrb. It would be nice if we could just have testrb back, but that must be weighed against the fact the TestUnit 2.0+ still uses it.
In any case, having a commandline tool makes it easy to run the tests without having to fuss with "automagically" test running via MiniTest::Unit.autorun. It also opens up the potential for more running options such as -Ilib and -rfoo.rb, etc. The class that implements the command could also be constructed in such a way the it could be used via code as well --which would be useful for a Rake task, for instance.
