Add win and hidewin scripts

Win provides an easy way to hide and show windows (aswell as
optionally SIGSTOP and SIGCONT their processes).  Hidewin is a
simple wrapper around win which allows you to select a window with
"xdotool selectwindow" instead of from a list of all visable windows.

(Caution: Some windows don't want to be shown, so best practice
would be to only show windows you've hidden yourself. Example:
Firefox had/has a window which, when shown, will crash dwm (or X,
I don't remember).)

+# Map, unmap, suspend, and resume X windows
+#
+# There are 4 commands: hide, stop, show, and toggle:
+#
+# - Hide unmaps windows without sending SIGSTOP to _NET_WM_PID
+# - Stop does the same, but does send SIGSTOP
+# - Show sends SIGCONT and maps windows
+# - Toggle toggles between stop and show
+#
+# Caveat: Commands, for the most part, only change what windows are
+# listed in the menu. Thus, an arbitrary window id could be entered
+# and could be treated in an unexpected way.
