Printing: support the "Border width" setting for templates

Going to "Template -> Edit" now has a field to enter the
border width (in pixels as only that makes sense in CSS as a flexible
unit, TMK).

This field modifies the template_options.borderwidth Grantlee
property which is part of the bundled templates already
and allows the users to modify the borders of tables.

The C++ implementation was missing, while the HTML (template)
implementation was already in place. Overlooked during GSoC.
