Subject: Initial Support for Rich Replies

Add placeholder UI for showing replies in the text entry widget.
Existing quoting capability has been removed (Temporarily), as
it was replaced with the new reply capability.  Replies sent from
nheko do not currently appear correctly in the timeline (this
will be fixed in a future commit).
