Feature Request: Edit trusted key servers for matrix via the TUI

[jessebot]

Describe the feature you'd like, and why

Right now you can edit trusted key servers for matrix via the config.yaml file, but you can't do it via the TUI, even though the data does display to some extent in the TUI directly.

I keep being too busy to do this, so estimate is probably around a month or two, but if someone else would like to take this on, I'm happy to guide them if they need help :)
