Web-browser integration

[KitsuneRal]

There's a growing case for Quaternion to take a link or a shortcut from the browser and open it. While we still don't have the Matrix protocol scheme officially coined, possible options include:

• use a scheme unofficially
• have websites generate a simple shortcut file that would have an extension/MIME-type Quaternion could be associated with
• have an integration WebExtension that Chrome and Firefox could use, plus a plugin for IE

The last option seems the least convenient for users but doesn't need anything from the website authors. The two former options are roughly equal in the level of (in)convenience for website authors and for the audience, it seems.

https://github.com/matrix-org/matrix-doc/issues/455 is the issue about the scheme, ftr.

@KitsuneRal I would be really happy to participate in a scheme proposal, even if unofficial to move things forward. I would integrate it into the various Kamax products - so you have my support for option 1 if we can debate it a little bit like we did for .well-known

The URI scheme is there, what remains is making Quaternion understand and dispatch (via some single-application-window framework) URIs passed as arguments.
