Certain URLs with the format:

https://(canary.\|ptb.)?discordapp.com/channels/{serverid}(/{channelid}(/{messageid})?)?

...are special-cased in the official client(s) to switch to that server or channel, or jump to a message in a channel's history, if the user has access to them. It would be awesome if ripcord could do this too.

Strongly related but possibly worth separate tickets: clickable channel mentions and an option to jump to pinned messages.
