StandardNodule : Use "nodeGraphLayout:label" not "label" metadata.
StandardNodule : Use "nodeGraphLayout:label" not "label" metadata.

The "label" metadata is typically registered to simplify a name taking into account the NodeEditor section it will appear in. Using the same label in the NodeGraph makes no sense, because there is no section there to provide a context. This was totally breaking the AlSurface UI.

Using a "nodeGraphLayout:" prefix allows us to provide a label better suited to the context. Over time my intention is to refactor most of the "nodeGadget:" and "compoundNodule:" metadata so that it all becomes "nodeGraphLayout:" metadata instead, and is analogous to the "layout:" metadata we use in the NodeEditor and the "toolbarLayout:" metadata we use in the Viewer. This will involve refactoring CompoundNodule and StandardNodeGadget to make use of a NoduleLayout class.
