[dwm] beta dwm-5.0

Apart from the consideration if I will add keyboard-driven
floating client resizals (haven't decided yet, due the lack of
demand for this, but if it will be introduced, I consider using
the arrow keys as shortcuts for this) I ask you to heavily test
hg tip now, because it is in a state which I consider beta and
which won't change a lot.

Kind regards,
