Update selection list items on history changes

This is necessary for handling undos/redos during
multiselection. For example: change a feature's preset
or name, select the feature and some others, undo: the
selection list should update to display the former
preset type and former name.

While here, I removed the object indirection and bound
entities directly, and I removed hover effects (since
the features are selected, you can't see the hover).
