*fixed regression in the editval function that prevented proper updating of the GUI edit/perform button and other related visual cues

*added recursive checking for when objects are selected to properly reselect arrays nested inside GOP subpatches/abstractions. This is important because the implementation should work for any level of depth. Later consider making this a more universal check should such prove necessary (I think once we move away from redrawing the array every time a point is moved, all this will become moot)

*fixed bug where recent files did not construct a proper path+filename when invoking it from a command line (at startup)

made a simple animation (toggle visibility) when tracking an error associated with a toplevel canvas. Use broken box font colors for error link in console.

Added methods to change coordinate data for shapes: data, points, x, y, height, width, cx, cy, r, x1, y1, x2, y2, and rx, ry for ellipse

fixed rx and ry methods, update scrollbars when scalar is displaced, and update bbox on changes to visibility and stroke-width
