[Xmonad] darcs patch: extract Properties module for re-use by contrib tests

Thu Oct 4 03:58:52 EDT 2007 Devin Mullins * extract Properties module for re-use by contrib tests I want to reuse Properties' Arbitrary instance (as well as the T and NonNegative types) in an upcoming set of SwapWorkspaces QC props. `module Main where import Main` doesn't work too well. :) If this patch is accepted, the darcs 'test' pref should be modified to "-itests tests/Main.hs".
