Subject: [PATCH] Closemon(), newmon as parameter

This allows to fix output-management: move clients to the monitor on the
left of the disabled one, instead of the leftmost (which might happen to
be the disabled one)

Also using wl_list_foreach() and then brake after the first iteration is
ugly and inefficient
