Review request for Plasma, igorto and Adenilson Cavalcanti.


Summary
-------

A new property "isBounceable" is added to the Rotation animation, which causes the target widget to "bounce" on a range between (-angle()/2, angle()/2). A static number of steps is defined by default (10 steps), causing the bounce angle to decrease through the animation steps. Notice that this effect doesn't behaves properly when the animation is part of a group, falling back to the "non-bounceable" behavior when it is part of a group.

Testing
-------

Tests have been made for different angles/axis on an additional example button on the animation plasmoid example. This example code is not yet release, but I can kindly pastebin it if needed.


Thanks,

Bruno
