Support for International Charaters

[oldiron-ho]

When using Korean characters label, removing labels make some error.
It seems that international charaters in a label cause encoding problem.

git-labelmaker/bin/index.js

Lines 123 to 125 in dbe537f

	if (confirmRemove.youSure) {
	return gitLabel.remove(configGitLabel(repo, token), answers.removals);
	}

Above code should be

          if (confirmRemove.youSure) {
             answers.removals.forEach(function(removal) {
                removal.name=encodeURIComponent(removal.name);
             })  
            return gitLabel.remove(configGitLabel(repo, token), answers.removals); 
         } 

I confirmed that the problem was resolved.
