Everything works:
	Hexchat
	Mango IRC
	AndroIRC
	Lite IRC
	Mutter
	Weechat

Usable, with bugs:
	HoloIRC
	- No client tag support, upstream bug https://github.com/tilal6991/HoloIRC/issues/140
	AndChat
	- duplicate usernames appearing. possibly an upstream bug https://github.com/znc/znc/issues/424
	Irssi
	- Ignorable warning "critical nicklist_set_host: assertion 'host != NULL' failed"

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