make the argument parser for commands accept quoted strings, while i'm

there make u_spawn use exec_wm (renamed to u_exec) for it's execution to
remove duplicated code.

This means constructs like this work in .cwmrc:

bind CM-t "ssh -Y 192.168.1.2 \"xterm -e top\""

or alternatively:

bind CM-t "ssh -Y 192.168.1.2 'xterm -e top'"

"in it goes" okan@.
