Send_ConfigInfo: don't send monitor info

When a module requests information about what it needs to know, it does
so to fvwm by asking "Send_ConfigInfo".  However, if this happens, and
fvwm is already sending information to all modules (such as via a
DesktopSize command), then an infinite loop can take place.

Fixes #997
