Creating a new SBT project throws an exception about creating a window outside of the EDT thread

[akochnev]

I built and ran the plugin with the latest sources. When I create a new SBT project from the New Project menu/icon, this exception is thrown. It doesn't prevent the project from being created.

It looks like NetBeans decided to be a bit more strict if a window is open outside of the event dispatcher thread.
