Move 3.1.3

ignore disabled filters

Fix source transition initialization

Use average z order of items

switched disappearing and appearing items

Warning: properties have changed since version 1.0.x this resets some settings.

• Split easing and curve properties for matched items, appearing items and disappearing items.
  Now you can give appearing items an other curve and easing than disappearing items.
• Added a override filter.
  You can use this filter on a source or a scene.
  If you use it on a source the override is used on all the scenes the source is used in.
  If you use it on a scene you can select the source of that scene that is affected.
• Added positions (Left,Top,Right,Bottom)
  This allows you to swipe sources in a direction instead of towards a point.
