Message:

Add panning action

• Use by shift-left-click and dragging the mouse, or by adding a "Pan" action
• Mouse binding is disabled by default, enable via "MousePan" setting in in settings/experimental (also "AutoWrap" setting was moved to experimental too)
• Frames now save all visible items instead of deleting items that have negative position values, this change was made so items would not be lost by panning the frame.
