xwm: Fix the window decoration hints.

Enable all hints by default. This fixes the "Maximize" button in apps that
don't set any hints - e.g., xclock or Firefox. (There's still a problem, though:
"decorate" is sometimes treated as a boolean, sometimes as a bitmask.)

Handle MWM_DECOR_ALL correctly. It looks like it's supposed to invert the values
of the rest of the flags.
