T1002191 enable new wizard elements

I found a way to auto enable new wizard entries. Together with #748 this solves the last known problem of the new wizard.

They get only enabled once (the first time an IDE with the new wizards is started) and then never again.
I know this isn't part of this PR, but I really don't like that now we have icons and menu entries coming from this, labeled Nodeclipse. It looks slightly unprofessional. Do you think we could get rid of this dependency? Depending on the license, we should just include the actual code (but not in Java form, of course).
