Custom widget frame styles such as 'Sunken' and 'Raised' which seem to
varry between OS will be captured as well:

So instead we temporarily set the profile frame to QFrame::NoFrame and
then restore it to the previous value.

PrintLayout::printTable():
- hide the QTableView widget border using a stylesheet
- add a guard to fix the last column extending post the page width
due to rounding
- use 1 extra pixel instead of 2 when grabbing the page region

This patch adds a couple of classes and some other modifications
in PrintLayout that handle the printing of tables under a profile.
models.h : ProfilePrintModel
The class uses a 'struct *dive' to output all required data
for a certain dive at specific rows and columns. It also handles
font formatting and text alignment.
modeldelagatates.h : ProfilePrintDelegate
The class is used only for drawing a custom grid for profile tables.
PrintLayout::createProfileTable()
The function is used to create and setup the profile table object
PrintLayout::printProfileDives()
The function now has correct padding of dive profiles on a page
and also the printing of actual tables below them.

printlayout.cpp(h):
This patch cleans some test code and adds the function
printProfileDives() that accepts a number of dives
per rows and columns. It can technically fit any number
of dives on a page given the page size allows it. Both
landscape and portrait layouts are supported.
It now replaces the old methods:
printTwoDives()
printSixDives()
Space is reserved for data tables that will be placed
bellow profiles on a later stage.

The current QTextDocument implementation is slow due to
HTML parsing. By using QTableView with QAbstractTableModel
we boost the performance of the table print drastically.
This patch completely replaces the old solution.
There is a hidden QTableView widget which is populated
with all data and rendered using a QPainter attached to
the printer device.
A couple of new classes are added in models.h/cpp
that handle the table print model and these are then used
in printlayout.h/cpp.

We pass the value of 'color_selected' stored in the
print options to ProfileGraphicsView::setPrintMode().
This way the profile can be printed in grayscale
internally instead of converting a QPixmap to
grayscale.
There are a couple of questions here:
1) Are all the 'if/then' checks for all individual
colors faster than the direct QPixmap/QImage grayscale
coversation.
2) The direct grayscale conversation does not give
control of individual colors, but can it look actually
better?

(experimental)
Add the method PrintLayout::convertPixmapToGrayscale()
to convert a rendered profile pixmap to grayscale.
It will probably be faster to have
ProfileGraphicsView render in grayscale under certain
conditions (and use a specific color table) instead -
e.g.:
ProfileGraphicsView::setPrintMode(bool printMode,
bool useGrayScale);

PrintLayout::printSixDives() goes trough all dives
and prints their profiles on full portrait pages.
This method is based on resizing the ProfileGraphicsView
widget, plotting each dive and then 'grabbing' it using
QPixmap::grabWidget().

There is a potential issue when placing a heading on a new
page. If the height of a data row is larger of that of
a heading, a new heading can end up at the bottom of a page
leaving that page with two headings.
To solve that we add line breaks (<br>) until the new
page is reached and add the heading there. Algorithm
assumes that the height of a heading is larger than
a line break. Also it is now obviously even slower.

QTextDocument uses a separate painting device,
thus we need to pass our QPrinter instance which may
have a resolution different from the screen resolution.

Currently only for the table print, but now we use the
actual dive table to iterate trough all dives (find only
selected if needed) and print their 'number' element
in table rows.
Also improves the new-page detection algorithm slightly.

PrintLayout for now only handles the table print,
while the data output itself is work in progress.
For now there is a simple HTML/CSS table logic based
on QTextDocument. There is an iterative algorithm
which listens for a page increase and adds a heading
on top of the new page.
