BigBlueButton 2.3-alpha-7

This release of BigBlueButton 2.3 includes multiple bug fixes and several enhancements. Several significant configuration (setup) changes were made (described below).

Big thanks to comminuty members @amguirado73 , @schrd, @basisbit, @jibon57, @cod3r0k, @hiroshisuga, @maths22 and others! Thank you to all who tested previous alpha's and reported issues encountered!

Note that we removed the recently introduced in 2.3-alpha5 instanceId from the HTML5 client's url. You may need to edit the following two lines in /usr/share/bbb-web/WEB-INF/classes/ if you are updating an existing 2.3.x server.

- defaultHTML5ClientUrl=${bigbluebutton.web.serverURL}/html5client/%%INSTANCEID%%/join
+ defaultHTML5ClientUrl=${bigbluebutton.web.serverURL}/html5client/join
- defaultGuestWaitURL=${bigbluebutton.web.serverURL}/html5client/%%INSTANCEID%%/guestWait
+ defaultGuestWaitURL=${bigbluebutton.web.serverURL}/html5client/guestWait`

Also, if you develop on top of the HTML5 client and run from source code (via npm start) you will need to make a change in /etc/bigbluebutton/nginx/bbb-html5.nginx so you do not use the html5 pool (comments are in the file)
