Added support for showing the Stars on the DiveTable

For the stars on the dive table I had to rework a bit my
StarRating widget, because it used a pixmap for each widget
that were created. Not it uses only 2 pixmaps: the active
and inactive ones.

A new file was created named modeldelegates(h, cpp) that
should hold all delegates of the models. For the GTK / C
folks, a 'Delegate' ia s way to bypass the default behavior
of the view that's displaying the data.

I also added the code to display the stars if no delegate
is set ( good for debugging. )
