Nodes now have the ability to snap to the center of their parent node.
Fixed issues with sub nodes' alignment lines not drawing in the correct
location when in scaled parents
Fixed some line refreshing issues when zooming in and out of the stage
or when scrolling

Known issues:
This only works when parents’ anchor points are 0, 0

To Dos:
Make the position of a node update in the property list after it snaps
Multiple selection alignment/snapping
Anything else I come across
