Render message links in a special way

[Bios-Marcel]

What do you want

Currently message links are just a normal URL, however, this will cause the terminal to open the browser when clicking the URL. Instead the user should get a special rendering, like mentions and channel-links get one. Then there should be a context sensitive action that allows jumping to the message. If there are multiple links we could open a choice dialog or so.

Why

It's annoying that you have to use two different clients.

Might be a part of #43

I just changed my mind about this. Instead of rendering it like a link, it could instead be rendered as a quote. Basically like how quotes are sent when quoting another user by selecting a message and hitting 'q'.
