New Adapter for MiniTest 5

[trans]

MiniTest's API changed to (finally) support custom reporters properly. Turn needs to be updated to support this new API.

Basically this means the MiniRunner class can probably be simplified to almost no code, and the heavy lifting will be taken over by an interface adapter between Turn's Reporter class and MiniTest's.

But it may be prudent to do this in such a way as to retain support MiniTest 4 still --on the other hand we could just require that users update to MiniTest 5.

I just pushed preliminary support to master. I guarantee some things are quite broken, but the basics are at least working.
