Also fixed a few GUI invocations previously done from threads other than EventDispatchThread.

> Lots of synchronization in the Modeler code points to our earlier misunderstanding of Swing single-thread GUI update model [1]. We should remove synchronized blocks from the UI code, and at the same time ensure SwingUtilities.invokeLater is used from other threads when updating the GUI. Most notably - ProjectWatchdog thread.
