Imported sbt.Process into trunk, in the guise of package
scala.sys.process. It is largely indistinguishable from the version in
sbt, at least from the outside.

Also, I renamed package system to sys. I wanted to do that from the
beginning and the desire has only grown since then. Sometimes a short
identifier is just critical to usability: with a function like error("")
called from hundreds of places, the difference between system.error and
sys.error is too big. sys.error and sys.exit have good vibes (at least
as good as the vibes can be for functions which error and exit.)

Note: this is just the first cut. I need to check this in to finish
fixing partest. I will be going over it with a comb and writing
documentation which will leave you enchanted, as well as removing other
bits which are now redundant or inferior. No review.
