Improve moderator experience

[coffee2code]

Moderating a photo involves assessing and possibly assigning values for a number of fields. It can be easy to overlook things, so the admin interface should provide cues to the moderator for those things that especially need attention. Also, interface elements that don't need assessment or shouldn't be used should be removed to reduce the clutter and streamline the moderation experience.

This is a bit of a catch-all ticket as I implement a few things I already have in mind, and for future related changes. These include:

From admin listing of photos:

• Remove the 'Colors' column from the listing of photos in the queue. Colors are no longer auto-assigned, so this column is almost always blank in this view.

For editing a photo post:

• Require assignment of at least a term for all custom taxonomies (category, color, orientation, tag) before allowing publication.
  None of the custom taxonomies should be empty. Report a failed publication accordingly.
• Hide the "Orientations" metabox.
  The value for this custom taxonomy is automatically set on upload and shouldn't need changing as long as a value got set.
• Highlight photo description when empty.
  Every photo should have a description.
• Highlight taxonomy metaboxes lacking any set terms.
  This should be dynamic and remove the highlight once a term is assigned, and highlight if all existing terms are removed.
• Hide the 'Author' metabox.
  Reassignment of a photo submitter will likely never need to happen. If necessary, this can still be done, but doesn't need to always be shown. Details about the contributor are already shown in the 'Photo Contributor' metabox.
• Remove the "+ New {term}" functionality for custom taxonomies when editing a photo.
  Category, color, and orientation terms are pre-configured and shouldn't be added on the fly. They can be added from the custom taxonomy management pages.
• Force use of the text editor.
  There is no need to facilitate making use of visual elements since no markup should be used.
• Remove 'Add Media' button and the quicktags toolbar for the text editor.
  Media shouldn't be added here, nor markup used.
• Prevent creation of new photo posts within the admin.
  Only the frontend submission form should be used. This should remove the 'Add New' photo button in various places.

Closing a fixed. Everything listed in the original ticket, and then some, has been implemented. I'll try to continue attributing moderator experience related commits to this ticket if they aren't otherwise associated with another ticket.
