ensure that listeners in the preference framework are properly namespaced

Currently there are listeners like the onReset defined in the fullNoPreview preference editor that aren't properly namespaces.
https://github.com/fluid-project/infusion/blob/master/src/framework/preferences/js/FullNoPreviewPrefsEditor.js#L33-L37

This means that if you want to use the fullNoPreview prefs editor but want a reset that doesn't save, you won't be able to use this base grade. There is no way to override this event, as providing new configuration will just merge.

The entire preference framework should be examined to resolve similar issues.
