Be able to copy a group

[Robert Lyon]

Allow group/site admins to be able to copy a group.

The things to copy should be:

1) The group settings of the original group.
- Will need to adjust the group name similarly to the way copying a page works to avoid duplicate group names.

2) Pages/collections in group.
- Will need to be done the same way copying a page/collection works now so that any copied files end up in a 'viewfiles' folder in the Files section.

3) Copying journals like we currently do when they are placed into a page.
- If a journal is placed into two pages that are copied, it's only copied once.

4) Copying of the old group homepage will need to be done instead of using the default homepage created via template.

5) Copying files like we currently do when they are placed into a page.

Bug 1594579: Allowing a group to be duplicated

This patch does the copying of:

- The group settings - and renames the group to a new unique name
- Views/collections - the same way we copy them now so that copied files
end up in 'viewfiles' folder.
- The group homepage by copying the old homepage like a normal
page then move the blocks from it to the new homepage and then deleting the
duplicated homepage.
- Adding copy buttons to the admin/groups list, the my groups list,
and group homepage.

Still to do:

Make sure we don't duplicate more than one copy of a journal if the
journal is within more than one page/block

Bug 1594579: Copy view artefacts only once

Rather than copy the same artefact once per page we should only copy
it once per copy of page(s) transaction. Eg if we are to copy a
collection of 5 pages and they all have a block pointing to the same
image we should copy that image only once not 5 times.
