#31 Allow closing/hiding private group messages 6 months ago

Ticket created by ~aloga on ~reedwade/wee-matter

Private group messages cannot be archived or deleted in Mattermost, but they can be closed in the Mattermost desktop and web applications, however this does not reflect on wee-matter. It will be nice to keep the list of closed group messages, removing them from the buflist (as otherwise the list may become gigantic).
