[dwm] dwm sloccount through the time #3

Hoi community,

I updated my dwm-sloccount-graph creating script.

First, it was not possible to run it on another machine with
mercurial-1.0, which has no 'strip' command :-?
However, I used `update -r <rev> -C' instead, which seems to be better
anyway.

Second, I added display of the dwm release numbers, for which I was
curious about. Some numbers are a bit hard to read, but I haven't
found a better solution for that ATM. Suggestions welcome.

Here is the data:
