Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
Before we use a tricky way to share mouse event between model render widget and model edit widget, which forward the event from render widget to edit widget. This will cause some problem, such as the scroll bar of edit widget would not work when it covered by the render model.
Now the mouse event is totally disabled in the render widget, and when there is a need we forward it from edit widget.
