Fix typo in default concept diagram config
WIP: progress marrying jsPlumb and GWT

Main insight: jsPlumb errors seem to be some sort of race, ie.
that you need objects to be in the DOM tree (?) before you can
do stuff with them.

For now, we trigger launches only on a button click.
Later on we will have to figure out how to either monitor the canvas
or have some kind of event triggered
