Add another print option, 1 dive per sheet.

Simply add a dive option on bigger surface, whith bigger fonts.
The size isn't A4 nor A5, but the size used by some popular paper
divelogs.
The modification performs better if we transpose the profile and
the text of the dive, because, if the notes are very brief,we get
an excess of white space at the bottom of the print.
