Breakout Meetings

This version fixes issue igniterealtime/pade#220 and consolidates all versions of Jitsi-Meet in Pade to a single version in the ofmeet plugin. As from version 1.6.4, Pade desktop version will be loading jitsi-meet from ofmeet and the code removed from the browser extension.

A number of meeting features that were only available to browser extension users are now available from ofmeet for both web and pwa users. These include:

Webinar mode allows a one or more participants to be panelists with both speaking and listening ability while everyone else will be a listener. This is used for conferences organised for briefings, church gatherings or lectures. Group chat and private chat is still available for all to collaborate.

Another useful feature that works well with webinar mode is the ability to create breakout the conference into smaller meeting rooms for informal discussions. This works well in church meetings for prayer groups or for tutorial classes in lectures. The meeting owner can reassemble everyone back to the conference manually or set a duration that automates the process.

Also included is the ability to add video captions/subtitles to the conference from three sources:

1. Instant chat messages
2. Audio voice to text transcription. This will depend on the browser vendor providing the service. Only Chrome was tested.
3. Static data that can be used to tag the conference.

The captions/subtitles are captured as WebVTT data in synch with the audio and video to be recorded client side on the participants desktop if enabled. The media is chunked into an external embeddedDB database and used to create HTML, WEBM and VTT files to playback the recording when it is stopped.

Participants can uplaod files and share with other participants. make sure the httpfileupload plugin is installed and enabled in Openfire for this to work. users can drag and drop files unto the large video screen to upload.

Finally, support is added for the CryptPad online collaboration platform that provides 7 real-time collaboration applications:

1. Word processor
2. Code Editor
3. Presentation Editor/Viewer
4. Spreadsheet Editor
5. Interactive Polls
6. Interactive Kanban
7. Interactive Whiteboard
