Artworks description have own CKEDITOR. This is a hack!!!! Issues: 1) The special editors have to be called by their IDs. 2) All editors after the first special editor will be broken!
FIX: Zoom needs to be above the broken CKEDITOR crap or else it will be broken too.
FIX: Don't break if no artwork description.
.listable CSS class signifies man content whose inner content is available for listing by row or card
Improved artwork description layout.
