Recommended Content settings iteration

[jeffpaul]

Is your enhancement related to a problem? Please describe.

The current Recommended Content block takes input from a user via several controls, two of which are the Categories and Tags multiselect boxes. Let's look into an iteration here that:

1. Sets the Post type field to the same post type for the currently edited post type (e.g., if editing on a Page, then set the Post type to Page).
2. Set the Categories and Tags to be the same as the currently edited post type (e.g., if editing on a Page that's set as Categories=Sports, Tags=[Soccer, Technology], then set those categories and tags as the default ones for the Recommended Content block).
3. Add a Use this Post's Categories and Tags toggle that defaults to enabled and sets those fields based on Integrate Watson API for image recognition #2 above. This makes those fields uneditable (or alternatively hides them). Disabling this toggle makes the Categories and Tags fields editable.

Props to @jakemgold for the inspiration on this UX improvement.
