Add tank data to the print.

Browse source 
Add info of the used tanks, which isn't displayed by the
dive plot, with a new function.
The relative width and height are fixed in print(), so the function needs:
 - Modify the font size depending on the number of tanks.
 - As it uses translations, return to the original coords when ends.

Modify print() acordingly with the new function.
