TypeError is thrown when attempting to post to mediawiki

When I try this:

var MediaWiki = require('mediawiki');

var bot = new MediaWiki.Bot({
    endpoint: "https://en.wikipedia.org/w/api.php",
    rate: 60e3 / 10,
    userAgent: "ExampleBot <https://en.wiktionary.org/wiki/User:Example>",
    byeline: "(example bot edit)"
});

bot.login('my_username', 'my_password').complete(function (username) {
    console.log(['Username:', username].join(' '));

    bot.edit('User:My_Page', 'Testing via API', 'This is a test.')
        .complete(function (title, revision, date) {
            console.log(title);
            console.log(revision);
            console.log(date.toString());
        }).error(function (err) {
            console.log('Error');
            console.log(err); 
        });
});

I get this:

TypeError: Cannot read property 'result' of undefined

When I console.log the data variable on line 484 of mediawiki.js, I get:

Username: my_username
{ servedby: 'mw1189',
  error: 
   { code: 'mustposttoken',
     info: 'The \'token\' parameter was found in the query string, but must be in the POST body',
     '*': 'See https://en.wikipedia.org/w/api.php for API usage' } }

I'm looking to possibly address this issue and/or add some enhancements, but was wondering if you were still maintaining the repo, @oliver-moran ?

Also, @oliver-moran , are you set on using the GPL or would you be open to a more permissive type like MIT?
