Do nothing when clicking non-participating country

Gives the visible improvement that you don't get a non-participating
country being highlighted, whilst maintaining the previously clicked
country's votes
Framework for displaying results of "to_country" etc.

Soon, I will add buttons so that the user can switch between voting
modes.
But first, let's get those voting modes working!
to_country voting display now works

It's still hardcoded as from_country in the config file, though.
Need to add a button next, to change this.
