Create movers eagerly so they always show in Toggle Anchors

The Extra Action Button, Instance Swap, and class resource frame
movers only got built once their native frame had already appeared
on screen with a resolvable position -- so if the frame never showed
up in a session (e.g. a class resource bar the current class doesn't
use), Toggle Anchors had nothing to display for it. Movers are now
created up front from a default size/position, and just get resized
and anchored once the real frame shows up. Also fixes each mover's
right-click config shortcut, which pointed at a pre-restructure
options path.
