IMO this should go into a pure JS file. Behaviors are are like polymer base
classes and should be use to facilitate UI related functionality.
Anything that can be in pure JS should be in pure JS, so when we switch
frameworks or move to the next version of Polymer we have to port minimal amount
of code.

From the docs:
"Polymer supports extending custom element prototypes with shared code modules
called behaviors."

This is the Polymer way to have shareable js, not raw js files.  I'm going to go
with that.  It won't be hard to port in either format, and this one will be less
confusing to other Polymer developers who come in from other Polymer projects.
