API - Message threads

[nickvergessen]

• Overview at Thread/"Respond to single post" option #1469
• Rough idea is that when a reply message or a message that has a reply is clicked, we filter the chat stream with that "thread" ID (root parent message).
• All newly written messages should be addresses to that root parent as well (needs a new API parameter, so that you can still reply within a thread for quoting and reactions)
• The UI of course needs to see a button to "go back" to the unfiltered list.
