fix removal of helf attachments

Left out confirmation of removal for held attachments because
a) they're not in the wiki yet, so confirmation is a bit unnecessary
b) it would be hard
c) eases later integration of jquery file upload interface

Also changed where attachments of index are held (to match where they're
stored in the srcdir).

Note that the attachment formbuilder hook was made to run last, so that
the list of attachments is not generated before removal, in the fast path
w/o confirm.
