[dwm] [patch] Tomati patch for 4.4.1

Hi all,

I just wrote a small patch to dwm 4.4.1 called tomati (for
TOggleMAxTIled). It's purpose is to allow the use of the togglemax
function on tiled windows. I tested it a little and it seems to me
that it behave as it should be.

But as it is the first patch I submit, and not only for dwm, there may
be problems I didn't see. Of course feedbacks are really welcome.

And thanks again for this really great WM !
