Printing: Add TemplateLayout class

This is the main class to hold Grantlee engine logic.
TemplateLayout::generate() loads QT5Grantlee and initialize the
templates then returns a QString that contains the rendered HTML by
Grantlee library.

Also this class contains the Dive class which holds the logic that
formats the data before passing it to the templates.
