Consolidate jitsi-meet for browser extension, web and hosted versions.

Jitsi-Meet was embedded in Pade in order to integrate it better with Openfire and extend it with more features independent of the Openfire Meetings plugin for Openfire.

Pade can now be accessed from three different contexts

1. Desktop - Installed browser extension/addon web store (chrome, edge)
2. Web - As a web/pwa application from the pade plugin for openfire
3. Hosted - As a web/pwa application from GitPages using a cloned repo of Github

Pade uses a customised version of Openfire Meetings for web/pwa contexts. Supporting two different versions of Jitsi Meet with varying features is confusing and not sustainable of a long time. It makes sense for the browser extension to also use Jitsi-Meet from the Openfire Meetings plugin.

Done. It will be available in version 1.6.4
