This fixes the labels on the execution stack for nested nodes.
Also fixes the cross selection issues between the stack and the graph views.
Finally also implements the "focus on selection" feature, which will now open the right tab and focus on the selected nodes.

Since a new wire can disconnect an old wire - we need to ignore certain wires when building the map for link validation and cycle checking. With this fix we pass a list of links to ignore (wires to ignore in the graph) to the AST that's going to get build, and then perform cycle checking only with that.
