Title: resolves #211: run tests in parallel

@kevgo @allewun

Type | Run 1 | Run 2 | Run 3
--- | --- | --- | --- |
Without parallel | 2:24 | 2:26 | 2:22
With parallel (8 processors) | 0:36 | 0:38 | 0:37

* Had to give each thread its own repository base so they don't overwrite each other.
* Moved formatter to `rerun` (prints just the failing tests) as the other formatters don't look very good when outputting in parallel.
* Removed fuubar formatter as not used anymore (does not work well with parallel)
