Would like to see BIP21 Bitcoin URI Schema support

[imcoddy]

Hi

Thanks for the hard work for creating this.

If possible I wish there is a feature for this extension to support Bitcoin URI schema. After install and click on a link like bitcoin:12A1MyfXbW6RhdRAZEqofac5jCQQjwEPBu?amount=1.2 then it can pop up automatically. This will be a killer feature to turn this as a handy hot wallet.
