Members of private channels and threads not shown

Members for DMs and public channels show, but for private channels and threads, the members are not shown.

I have this issue with senpai: Only things starting with "#" or "&" are classified as channels (chantypes). "@+" are prefixSymbols.

We should send a CHANTYPES message so it knows that @ and + are valid symbols for channels.

Oh, we are sending CHANTYPES, but senpai is reading it as an error:

Received corrupt message          
":localhost 005 zach.decook
