Subject: [PATCH] Add completely BS dive text printing

The layout is crap, the handling of long lines in notes (or location) is
wrong, the dive number handling is wrong.

The thing is just a toy.

But it's a toy that kind of works, and gives a much better idea of what
a real dive log printout might look like.  With the right kind of dive
notes, it looks fine.
