Some enhancements to country codes could be made

[ghost]

First, I'd like to thank you for implementing country codes. While it's there now, some enhancements could be made.

I just saw this and it'd be much easier for us to change the country code from the reply window with a dropdown menu with all of the imageboard's current country codes instead of opening the app > opening the menu > clicking on the imageboard > clicking on country flag code > figuring out the country code > putting in the country code.

What do you think?

Per the comment I left on #591, I'll accept a PR.
