Password Reset support

[ike]

Poop, the password reset section in ember-authenticate-me wasn't reusable. Can we make it reusable in the library instead? Something like this in addon/controllers/reset-password should work:

import Ember from 'ember';
import getConfig from 'ember-authenticate-me/configuration';

export function resetPassword(error) {
      const emberAuthenticateMeConfig = getConfig();
      const PASSWORD_RESET_URI = emberAuthenticateMeConfig.passwordResetUri ||
        '/api/password_resets';

      if (!error) {
        return new Ember.RSVP.Promise((resolve, reject) => {
          return Ember.$.ajax({
            type: "PUT",
            url: [PASSWORD_RESET_URI, this.get('token')].join('/'),

            data: {
              password: this.get('password'),
              password_confirmation: this.get('password_confirmation')
            },

            success(/*data*/){
              resolve(...arguments);
            },

            error(err/*, text*/) {
              reject(...arguments);
            }
          });
        });
      }
}

Then in both the addon controller and in your code, it could be used like this:

import { resetPassword } from 'ember-authenticate-me/controllers/reset-password';

...

export default Ember.Component.extend({
  ...
  actions: {
    ...
    forgotPassword() {
      return resetPassword(this.get('errors')).then((/*data*/) => {
        this.set('requestSent', true);
      });
    }
  }
});

The catch part of the promise will work too. Let me know if that isn't clear.
