[dw-free] better shop workflow for renames

[fu]

[commit: http://hg.dwscoalition.org/dw-free/rev/c611987401d5]

http://bugs.dwscoalition.org/show_bug.cgi?id=3098

Have a note linking to the base /rename/ page while the rename token is not
yet paid for. (Once paid for, the link will be to the actual token on the
rename page)
