Feature/tooltip autoscroll

[tonihele]

Little bit quirky. Implements the tooltip autoscroll if it doesn't entirely fit to the allocated space.

• Somehow I could not get the style applied properly, so the component now has a fixed style set. Not a problem for us but annoying design
• The effect length is 70s, hmm, yeah, the effects time calculation is a bit difficult for this kind of task. I would have wanted infinite time but then we just get 1s always as normalized time. So now everything is normalized to this 70s, the delays and speed. Pretty annoying. The effect length should perhaps be take account in the math so that this length variable could be adjusted freely without the effect speed changing....

Edit: I fixed the math so that there are far less variables and more constants
