Banner parameters should be exported/pushed as objects so as to not break pre-8.2 Ghostery versions out there and sync properly.

@zarembsky Should we also handle a similar case when pulling settings?

This case is already taken care of in src/classes/Conf.js, line 80. Handling data conversion in this place also takes care of importing settings from file, which goes through invoking PanelData.set, which eventually invokes conf set trap.
