Printing: retrieve number of dives per page from the template file

Browse source 
Add special data attribute 'data-numberofdives' in the template <body> with
the number of dives per page.
This is standard HTML5 specification so it won't corrupt the template file.
Any template that will be used for printing must contain this attribute to
assure correct output.
