Make newer prosemirror controls available in editor toolbar

Need to specific the engine to the editor tag. E.g.,

{{editor data.system.description target="system.description" button=true owner=owner editable=true engine="prosemirror" collaborate=false}}

Need to figure out how/if to style the prosemirror toolbar (and select dropdown colors), as well as maybe adding our calling card font to the font choice dropdown. Start here: https://foundryvtt.com/article/v10-text-editor/

It's not clear that we need to switch to Prosemirror (from the current Tinymce editor) right now. I don't think Mork Borg particular needs Prosemirror's multiple writers support or more powerful features, the toolbar is basically the same, and Prosemirror is new enough that I don't trust all the bugs are ironed out yet. Maybe later?

Closing for now.
