Test & whitelist known post types for certain plugins about gutenberg-ramp

I think I know what's going on here.

The unloading mechanism we've defined here unloads Gutenberg in the post edit context, which is surely the most important place for this to happen. However, it allows Gutenberg to run in every other context since I think gutenberg_can_edit_post_type governs only the post edit screen and does not address other Gutenberg side-effects such as menu modification etc etc ... I bet, for instance, that the Gutenberg menu is present in wp-admin.

Ideally, we want the user experience to be the same independent of whether Ramp is running with the plugin not activated, the plugin activated and eventually 5.0. This would mean adding functionality to remove things like menus etc etc ... I'll see if I can work on something like that.

@rogertheriault if you're working on stuff this week could you have a look at the above?

Also -- the reason you're getting No route was found matching the URL and request method is because that post type probably doesn't declare show_in_rest => true which is required for Gutenberg support ... we might want to check this before attempting to turn on Gutenberg for a post type since nothing will work in its absence.

@mattoperry tempting, but unfortunately I've been stuck with some other tasks at home that have kept me busy this week.

Great point on the show_in_rest.
