add ParabolicManager in the plasmoid
--move all the logic around parabolic effect signals into one place, ParabolicManager. The ParabolicManager is responsible for triggering all the messages to tasks that are neighbour to the hovered task. This will help a lot to catch cases such as separators and proper clearing zoom.pull/1/head
