[FR] Session independent room URLs

[mrx23dot]

Logically room link should not depend on session/# stuff.

E.g. I cannot create a permanent link to this room without specifying the session
https://hydrogen.element.io/#/session/6666628226533056/room/!FpRSTRksQOmjeEHMnl%3Amatrix.org

so all I can do is to link https://hydrogen.element.io/ and manually select the room, which is an extra step.

This wasn't a problem with full Element.
https://app.element.io/#/room/!FpRSTRksQOmjeEHMnl:matrix.org

Or at least provide an extra url scheme where it uses the default session for given room.
