Move copy freemarker templates to new dir

I'm planning to add one for editing, creating and stuff.
Basic outline for new and edit.ftl

(but there are no routes or forms, so they won't work yet. ;-)
Form for copy editing (no function!)

Doesn't have any fields in it yet,
Move copy stuff to new URL

put works/:workId/copy/ in front of all copy actions.
Works controller has base routes for copies
Show Work objId in the title if there's no title
show objId if there's no title
Update icons, link to edit copies screen.
new copy works
Titles and panel headings
Copy editing and creation

Also fixed bug where copy wouldn't display with a weird copy role.
if the copyrole has changed this won't mess up ;-)
few more errors caught
Added drop down list for the copy roles

Stops people doing odd things.
