Analyzer tooltips in the viewer

[RadStr]

I will solve that later, since I have to make special section in the XML with all the tooltips for all the algorithms. I can't have the tooltip as element at the algorithm node (the infoNode), because usually there will be a lot of songs with the same algorithms, so instead of having the tooltip saved only once, I would have it saved every time it was used and since tooltips are usually at least one sentence long, it would take a lot of space.
