Remove doubleFork, handle SIGCHLD

Ignore-this: f9b1a65b4f0622922f80ad2ab6c5a52f
This is a rather big change.  Rather than make spawned processes become
children of init, we handle them in xmonad.  As a side effect of this change,
we never need to use waitForProcess in any contrib module -- in fact, doing so
will raise an exception.  The main benefit to handling SIGCHLD is that xmonad
can now be started with 'exec', and will correctly clean up after inherited
child processes.
