Automatically run tests on darcs record

```
darcs setpref test 'runhaskell Test.hs'

I have to figure out if there is an easy way to get QuickCheck to exit with 
failure status if one test in 
a suite fails. Otherwise the record goes through even when tests fail (but not 
when compile fails).

```
