Report overhaul

I've processed pretty much all of the comments in the printed version we got from mr Pouwelse.

Please render the file when reviewing and look for the yellow todo blocks. I've left the vulnerability analysis as a todo, same goes for screenshots. I've added todo blocks where I felt screenshots are necessary.
Introduction is not touched either.

Please see this as a proposal; it's a massive change and I understand if you don't agree with everything.

Peace out.

Fixes #246 
The problem then is that you create a somewhat weird model of the user, where he cares enough about security that he would use our app, in my opinion a relatively extreme measure in most of the western world, yet feels safe enough handing their device over to others  without problem. While I do think there's something to be said for this model, I'm still not entirely sure it fits our scope completely.
