Mixer + Proper Polymer Support

Since I last worked on this Beam renamed to Mixer.

I took a look at this module after about a year of abandonment and found it to be quite messy. This new release is designed to correct this.

• Removing JQuery
• Using Polymer Properly
• Reducing Magic Strings - I continually mixup subs, sub, subscription, subscriptions etc. Its confusing
• Making startup simpler

Once this is done we'll probably end up refactoring a bit more to use OAuth from the dashboard to workour which channel we are. Then it wont need any config
