remove dynamic keyword, handling it in fromJSON

After discussing this in person with @minrk, we decided instead of
passing this parameter around and special-casing javascript, it's easier
to just remove javascript from the display_order for the duration of
fromJSON, since that's the only place where dynamic was set to False,
and then put it back in at the end of the fromJSON call.
