rush 0.4 released. Some changes:

• Rush::Box#processes returns a ProcessSet, for syntax like this:

processes.filter(:cmdline => /mongrel_rails/).kill

• Daemonize shell commands: bash 'some_daemon', :background => true

• Pass args to rush on the command line to execute a one-off, like this:

$ rush 'processes.filter(:command => "ruby")'
