Methods should be chainable

[manthanhd]

// proposed
new Bot().train(topic, sentence).addSkill(skill).resolve(....)

// current
var bot = new Bot();
bot.train(topic, sentence);
bot.addSkill(skill);
bot.resolve(....);

Isn't it just enough to add return this; in each method? It will return the original Bot object so that all other methods are still defined.

@rafaelklaessen you are right. See pull request #17 for updates.
