This patch adds a JSON progress meter (I'll call it that to avoid confusion
with progress bars) to the bulk uploading of users, groups and group
memberships and the bulk export and import of users (LEAP), so the user can see
the progress of the operation and not just the submit button changed to
'Processing..' and whatever indication their browser gives while waiting for
content.

The bulk export and import are minor rewrites, replacing the old iframe based
progress bar and the associated multiple pages and additional template file in
the case of the bulk export, and the recursive redirect-to-self of the bulk
import.

To accomplish the display of the progress bar during the operation, we make the
PHP session be closed (read only) except when changes need to be made. This is
for the most part a straightforward change in session.php as it's the only
direct accessor. In other places, we replace direct accessing of the session
variable ($_SESSION) with use of the session class ($SESSION) so that it can
reopen the session, make the change and close the session again.

There is one more aspect to all of this: with previous behaviour, multiple
requests for the same session would queue, taking the session lock in turn.
After this patch is applied, they can proceed in parallel, allowing greater
throughput. There is no additional locking requirement because the issues are
the same as those already dealt with in allowing multiple PHP threads to
process requests from different sessions at the same time.

I have sought to make the progress meter nice and generic, so it can be used in
the other bulk imports and exports too.

Paradoxically, these changes don't just make the import seem to be faster, it
actually is.. at least in the case of users and groups.

Times for importing 1000 users, groups and memberships, averaged over 3 runs
each (Wall time, not CPU time - but the relationship is the same).

This patch contains:
- The export queue system where pages/collections on release from
submission are added to the export queue table ready to be archived.
- The export queue admin page showing what is in the queue to be
exported. The cron runs every 6 minutes. Queue items failed to export
are also shown here.
- The archive list admin page, where one can download the generated
leap2a files for the archived submissions.

In this patch you should be able to add things to the export queue by
either releasing a sumbission on a group that has 'archive
submissions' option ticked. This will add the archive to that archived
submission page, or you can also run a leap2a export from portfolio
export which will add the export queue and send you an email once the
export is done.

Things to note:
- The is a server busy function that stops the export queue from
running but I'm not too sure if the threshold is too low/high
- The export queue tries to export the first 100 items each run but if
resources are fine in handling that easily then the number could be
higher but I'm not sure of what will be a good number.
- Currently there is alsoe infrastructure like table columns for dealing
with releasing submissions from external systems (eg moodle) but that
functuionality is yet to be built.
- The checking of server busy in MS windows untested - may need to
just let MS ignore server busy check as there doesn't seem to be
standard way to check this.

Have made the headings for the select boxes be labels that actually
sit with the fields. This allows them to stay with their field for
responsive theme and small screen.

Have updated text to indicate exactly which box is being talked about
rather than using 'left' or 'right' in the text.

The four existing jointypes, 'open', 'controlled', 'request' and
'invite' are mutually exclusive, but they don't need to be so strict.
This patch introduces more flexibility in the way groups allow new
members to join.

* Group admins can always send membership invitations to a group, even
  if it's open or controlled
* Membership requests can be enabled for any group unless it has open
  membership.
* The grouptype now determines the set of roles available to a group,
  but no longer restricts the available join types.

The db upgrade will preserve existing behaviour apart from enabling
invitations on open, request, and controlled groups.
