[dwm] selected client title and border

Playing with all this color and border stuff I've wrote a pull request to
remove active client's title from status and put it on the client
itself but highlighted. The border is not highlighted.

I liked it much less than current "tip" behaviour. Indeed. Is less
easier to notice where the focus is (even with so homogeneus palette)
and the border being fixed doesn't get me sick.

Some hint about the implementation will be welcome (even if it's crude
for main dwm)

I plan to introduce a 2nd status message in the released tab.
This way I can have the current pseudo-permanent text message and use
the tab on the right of mode indicator for messages with a
click-to-dismiss behaviour.
For personal use, of course ;)

thx,
