Tiny panics without visible message when nicks is an empty list

[e00E]

Default configuration but nicks is [] for freenode.

Then run tiny. A message flashes on the terminal but disappears immediately before I can read it. By redirecting stderr to a file I can recover this:

thread 'main' panicked at 'called Result::unwrap() on an Err value: Os { code: 25, kind: Other, message: "Inappropriate ioctl for device" }', libtiny_tui/src/tui.rs:69:18

If you need a way to get around this, the following works:

      nicks:
        -

Thanks for reporting. So first of all we should improve error reporting. Printing to stderr is not helpful in a TUI app. In the worst case I think we could redirect stderr to a file, but I think ideally all errors would be shown in tiny. Not sure if that's easily possible.

Secondly I think we should improve checking user errors in config files.
