Don't show "Move" item in drop menu for source files accessed using http
Even though the http protocol technically supports deleting, this is never implemented or relevant for a drag operation. Special-case this in dragjob.cpp so that we don't show a broken "Move" action in the drop menu when dragging stuff out of a web browser.
