[patch] Prettier printing

[Patrick Valsecchi]

In Qt4, QWidget child classes are printed as bitmaps. So appart from 
changing the code to print the tables to use a QGraphicsView instead, 
there is nothing we can do.

At least, with my patch, we get a vectorized profile and a nicer looking 
table (way higher resolution).

In attachment, a new version of my patch (merged with new head).

By the way, to compile, I had to add a translations/subsurface_source.ts 
file. I think we have a problem with the current HEAD.
