Preview output should be identical to the actual printing code, so
call the flow rendering method for all flow templates.
Also don't create new pages while rendering a one page preview, just
exit after the first page is full.

QPrinter::pageRect() doesn't always return the correct value of the
printable area, which results in white horizontal lines of un-rendered
area at the bottom of each page, Use QPrinter::pageLayout() instead
which fixes the issue.
QPrinter::pageLayout() is added in QT 5.3, So use pageRect for previous
versions.

While rendering a template with "0" dives per page value, try to fit
as many dives per page but don't break a dive into 2 pages.
Use a dynamically sized view port to fit the rendered area only,
and don't render the full page.
All the Template elements that shouldn't be broken should have
the CSS class "dontbreak".

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.

This bug occurs in "table" and "flowlayout" templates, it takes place when
the size of the full web view to be rendered is not divisible by the size
of the view port (Page size), This issue is fixed by adding extra padding
to the bottom of the body so that the total body height is divisable
by the view port size.

This simply uses the relative size of the profile. This can result in
truly tiny text in print, but at least it's consistent and logical.
We could add some minimum value there but I'm not sure that's the right
answer, either.

The existing code (and templates) looked up dives by number and then used
that as index into the dive table. This worked exactly in one case: if all
dives were numbered consecutively starting with 1. While that is not an
entirely unreasonable case, it's of course not an acceptable assumption to
make.
This commit adds the necessary changes to instead look up dives by their
unique id. That's what it's there fore, after all.

When we calculate the number of pages to print we need to check if the
template doesn't define the number of dives per one page, then render as
much dives as we can fit in one page. A dive can be broken into many
pages.
