Third beta release of the WebEx Meeting Moodle module.

Changes:
Fix errors when editing or deleting a meeting created by a different user.

Current Limitations
===================
As this software is in beta, you should see the Limitations and Bugs list at:
https://github.com/merrill-oakland/moodle-mod_webexactivity/wiki/Limitations-and-Bugs

Highlights for this release:
- Backup and restore does not work.
- When a Moodle user is used to create or host a meeting, a new WebEx user is created for them, with the prefix setting prepended to
the username. If the email address is already taken, the user will be redirected to a field to enter their WebEx password. A
workaround for this is to change the users existing email address in WebEx from something like user1@example.com to
user1+webex@example.com. Everything between the + and the @ is ignored by email systems.
- Only Meeting Center and Training Center are currently supported.
- User WebEx passwords are stored in the database.
This is because WebEx doesn't provide a way or retrieving a token for authentication, we must send the password with each request.
