[dwm] dwm-4.4 is on its way

Well, there wasn't so much feedback regarding the new MASTERW
replacement with {V,H}RATIO. Anyways, I documented the new
shortcuts and added some sanity checks to the new tile()
algorithm, that it maximizes all master/stack windows if they
would get smaller than barheight in height.

I ask you to test hg tip now. If there are no serious bugs, I'll
release it in a couple of days.

Regards,
