DuckPAN: drop line splitting.

It's a lot of wasted cycles in 2014 to do this kind of thing.  If
someone cares, they probably have a terminal setting to do it.  If they
don't, the cycles are even more wasted.

Includes some message review work as well, in an attempt to make sure
this isn't insane.
DuckPAN: prepend log level on each line.

With the word splitter gone we can better format these messages such
that if they span several lines, they look "blocky" enough to logically
group.
DuckPAN: update some message outputs.

Having run this, I saw some places where the messages are less
appealing, now that each line ends.  This is fixing up some of that.
Covert DOS to UNIX line-endings.

I have enough trouble with the mixed tabs and spaces; I don't need this
hassle, too.
