[PoC] Bootstrap UI

[Mads Kiilerich]

I think it could make sense to attack the css problem from both sides at 
once. Both gradually and "invisibly" introduce bootstrap and cleanups, 
and working towards a new styling made from that may or may not be 
similar to the existing look. I guess it can be hard to develop and land 
a pullrequest that changes everything. I guess working on clean 
bootstrap styling will reveal some templating issues that could and 
should be fixed first. So no matter how you attack the problem: You 
can't be wrong ... if only you can make it work ;-)
