[Xmonad] darcs patch: Commands: refactoring to include in MetaModule

Hi, description says it all. ciao andrea Sat Jul 28 15:20:29 CEST 2007 Andrea Rossato * Commands: refactoring to include in MetaModule Just a small refactooring (well, now runCommand requires a command list, and I added runCommand' that will take a string to run it against the default command list) to include this module in MetaModule so that we can track it in case of API changes (this patch has been requested by Spencer).
