Hendrik Leppkes:
	Refresh the state of buttons when they are newly created.
	Added an assertion with an detailed error message to debug an error in the action button code.
	Securely hide the old Blizzard UI, thus working in combat
	Small improvements to the vehicle stuff
	Properly unregister the vehicle events if not using the Blizzard VehicleUI
	Properly disable our built-in VehicleBar if using the Blizzard art
	Added an option to use the default blizzard vehicle frame for vehicles (the art and all the fun)
	Fix FadeOut, we need to check if the mouse is over the Overlay now, and not the actual bar.
	Safety check for an error that really shouldn't happen.
	Fixed initial positions for all bars
	Fix the behaviour of snapping for the new bar positioning.
	Fixed behaviour of padding on alternate growth directions and fixed the alignment of the drag-overlay.
	Added options to adjust the vertical and horizontal growth direction
	Use our SavePosition function instead of LibWindow directly
	Try to preserve the old position properly during the migration to the new system.
	Added plumbing to change the growth direction of the bars. Currently always defaults to DOWN and RIGHT, as that is the "old" behaviour.
	First work on LibWindow-1.1 usage, plumbing for new bar resizing/button positioning
	Fix all and any white-space errors
