Everything works:
	Hexchat
	Mango IRC
	AndroIRC
	Lite IRC
	HoloIRC
	Mutter
	Weechat

Usable, with bugs:
	AndChat
	- duplicate usernames appearing. possibly an upstream bug https://github.com/znc/znc/issues/424
	Irssi
	- critical nicklist_set_host: assertion 'host != NULL' failed
		- still occurs even without blank nicks in room privmsgs

Unusable:
	Yaaic/Atomic
	- doesn't properly understand/parse the room join
	Atomic
	- crashes if a blank nick is used for room privmsgs (but PtokaX is fine)
