[scripting] Introduce redirect function Summary: Consider current implementation of the Squash effect: if a window was minimized, an animation will be started; if the window is unminimized and the animation is still active (that can happen when user clicks on app's icon really fast), the animation will be stopped and a new one will be created. Such behavior can lead to rapid jumps in the observed "animation". A better approach would be first try to **reverse** the already active animation, and if that attempt wasn't successful, start a new animation. This patch introduces a new function to the scripted effects API that lets JavaScript effects to control direction of animations. The prototype of the function looks as follows: redirect(<animation id(s)>, <direction>, [<termination policy>]) the first argument is an animation id or a list of animation ids, the second argument specifies the new direction of the animation or animations if a list of ids was passed as the first argument. The third argument specifies whether the animation(s) should be terminated when it(they) reaches the source position, currently it's relevant only for animations that are created with set() function. The termination policy argument is optional, by default it's Effect.TerminateAtSource. We can use this function to fix issues with rapid jumps in the Squash effect. Also, redirect() lets us to write effects for simple animations in slightly different style: first, we have to start the main animation (e.g. for the Dialog Parent effect, it would be dimming of main windows) and then change direction of the animation depending on external events, e.g. when the Desktop Cube effect is activated.
