I’ve just released v1.12 to BinTray.

## 1.12.0

This release is preparing for a v2, with some DSL improvements, and 
parallel test running by default.

Run tests in each root context in parallel by setting a system property dev.minutest.parallel.

Lots of internal rework to support our own test engine and speeding things up.

Starting to decouple the DSL from the test building.

Some very minor API changes that I don't think anyone will notice.
