Changing ProcAvi shapes doesn't always work

It seems like the first time you select a specific shape configuration, it doesn't load, but the next time you select it (by either looping through the whole set of shapes, or by going back), it does load. It's interesting to note that the attachment nodes do seem to move when you select different shapes, however the visual appearance of the shape does not change. It's like for some reason procedural parts isn't redrawing the shape, but I don't know what would be overridden in Procedural Avionics that would be blocking that behavior (especially on just the first time you view that shape)

Looks like using reflection to find the part volume is throwing errors sometimes, which invalidates the procedural part. However, procedural parts sends a message when volume is changed, so i think we can hook into that instead
