Printing: export border to templates

As there is a problem with sizing the borders in QWebView, "vw" sizing is not
working as supposed with border-width, As a workaround we export border-width
dynamically, so that border-width is relatively the same for all page sizes.

The border-width is equal to the page width / 1000 which gives a nice range
for borders for A0 - A5 papers, Also prevent drawing zero pixel borders
and use 1 px borders as the minimum border.
