[dwm] dwm-3.0

Hi there,

I created

  http://suckless.org/download/dwm-3.0.tar.gz

Now the TILESYMBOL accepts the %u format string operator which
is replaced with the current nmaster value.
Also, the mode label accepts Button{4,5} presses to de-/increase
the nmaster value by 1.
dwm-3.0 does _not_ allow nmaster==0, that seems to much like a
hack (you can aim that behavior anyways due to increasing
nmaster to a high value like nmaster > number of tiled clients).

Have fun,
