Change behavior of highlighting in tables / lists

[andped10]

Currently the highlighting in tables / lists follow the element that is hovered.

This behavior is suggested to be changed into a highlighting of the latest clicked element in the table / list. The main reason is to make if more clear in the GUI when other element depends on the element that was clicked in the table / list. An example of the is the slider on the fitting page that enables the user to manipulate the value for the latest clicked parameter in the table.
