Start re-working the print UI to allow printing tables with no profiles.

With this commit we add a checkbox in the "Dive details" tab of the print
window. This checkbox allows to print the dives profile or not.

If you don't print the dives profile, you get 15 dives on the page (instead
of 6 with the profiles).

Future work should include:
- Ability to choose what is printed
- Table layout vs the current one (if no dives profile)
- Ability to choose the number of dives per page (play with the font size for this)
