* Add a new way to extend the BigBlueButtonBN form via subplugins
* Allow subplugins to extends information via new tables and use it in
the edit form.
* Add a new cache helping with potential perfomance issues introduced
by recurring calls to find out about associated tables in subplugins.
* Recording formats should not be accessible to students unless specified as safe
* A global setting will now list all the "safe" formats for students
* A new capability 'mod/bigbluebuttonbn:viewallrecordingsformats' will allow users to
see all formats (as long as they can manage recordings also)
* Provide a way for external participants to be invited to a meeting by giving them an url/password
for external users (not registered in Moodle)
* Add guest access page with username and password prompt
* Add form and modify API calls to take into account guest login
* Add a form modal to add guest users emails
* Allow copy of link and password in both popup form and module form
* The guest should be approved by default. It should be intentional to let them
in without checks.
* Guest access URL and password should not be copied when duplicating or backing
up the activity.
* The mod_bigbluebuttonbn_meeting_info web service function now
returns guestjoinurl and guestpassword only for moderators.
* Redirect if user already logged in
Note: this will allow guest to connect to an existing and running meeting. The moderator will then
be able to adjust the guest user's right. For security reasons we do not yet allow moderators
to join the meeting directly (or start a meeting)
* Remove the setting "lock on join" and related settings
* Hard-code the lockSettingsLockOnJoin=true parameter on create when any of the lock settings is used.
Adds a new install script for the BBB module and a new upgrade step.
The BBB module now will be disabled by default for new installations
and also it will be disabled for the existing sites that use the
default BBB server configuration. Admistrators will be required to
confirm the acceptance of the related DPA prior to (re)enabling the
plugin once again.
* Only delete "Create" or "Update" logs when a recording has been effectively created
* Reschedule task if fail or logs are left over
* One task per meetingid
