[ANN] Introducing Crossbar snap

We have packaged and released Crossbar to the stable channel recently. Snaps and Docker images are our two main mediums of distribution. Currently the snap is based off CPython, though going forward, we will be creating a snap variant that is based off PyPy.

So start with $ snap install crossbar and make your IoT ideas a success :wink:
