Print: provide means for profile layouting

Browse source 
printlayout.cpp(h):

This patch cleans some test code and adds the function
printProfileDives() that accepts a number of dives
per rows and columns. It can technically fit any number
of dives on a page given the page size allows it. Both
landscape and portrait layouts are supported.

It now replaces the old methods:
printTwoDives()
printSixDives()

Space is reserved for data tables that will be placed
bellow profiles on a later stage.
