Move vs. Copy on Drag

We've struggled to get drag semantics right. What we have is powerful but not right enough to meet everyday authoring and refactoring needs.

Drag content between wikis should follow mac/windows convention. Makes a copy. Drag within a wiki does a move. ★

Only move items between origin pages or local pages. Everything else is a copy, including anything from ghost pages.

Drag a copy from template or ✔ revision.

Make recent-vistors a ghost page. Make ghost pages read only.

Drag within search results writes corrupted search-results page. See exception noted in Special Page Names.
