Connect for Lemmy App

I've liked using the keyword filtering for communities, but sometimes some keywords are too broad so that's when I'd like to be able to filter out the specific community instance so an example being community@instance

It's something I came across on Boost which I liked. It's called mute there. Would help keep specific communities from popping up when I'm browsing as a guest on an instance where I'm unable to use the account based community filtering.
