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.

(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);

It might be a good practice to declare certain class
'helper' functions as constant members. But I don't
think there are performance benefits to that other
than the readability ones.

Patch does:
- set individual column width and name
(held in tableColumnNames, tableColumnWidths)
- reduce font size in the table
- more small tweaks in the style sheet
TODO: finish printing all dive data

We don't really need includes of display.h and dive.h in
printoptions.h and printlayout.h or forward declartions
of 'struct dive' and 'struct options' in there.

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.

The setup() method will be called each time to obtain the
current printer settings. Also it calculates required scalling
based on screen agains printer DPI.

PrintLayout is a class that will handle the layouting part
of dive profiles, text, tables depending on the settings
of a QPrinter and the PrinterDialog and PrintOptions
instances.
