Kepler

While testing http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5146 , I came across some gui strangeness. To replicate:
- drag the Sinewave actor to canvas
- right-click open the actor
- make a change, e.g. reposition an actor
- right-click on the canvas and select Save Archive, saving to Sinewave2
- search component library for sinewave, drag out to canvas the found Sinewave actor from within the Sinewave2.kar * the green actor will not initially appear, you'll just see its ports. It will appear if you drag it a bit.
