[PULL REQUEST] GSoC Printing: part 6

[Lubomir I. Ivanov]

This is the last batch of patches from Gehad for the "soft pencils down" date. 
For those who have free time and are interested in the printing module
please compile and have a look at this update.

I have requested multiple revisions on how the bundled templates look, trying
to get them as close to what we had before. Of course, this an aesthetic topic
and they simply *can't* be optimal for everybody.

Mind that the core functionality itself is now done and the community can
start contributing to the bundled templates by extending the CSS/HTML. 
If you have some nitpicks or find bugs, let us know!

We are now pretty much waiting on user feedback, while in the meantime
Gehad will finish the documentation update. If more time remains the now
supported "statistics" print will receive more attention, but mind that
this is a bonus feature for this GSoC project.
