version value

@mattpap or @philippjfr do you have a preferred way for updating version information? Currently the DEVGUIDE.md shows the following.

Update package version

File	Entry	Content
ipywidgets_bokeh/__init__.py	__version__	1.0.0dev2
ipywidgets_bokeh/kernel.py	implementation_version	1.0.0dev2
ipywidgets_bokeh/package.json	version	1.0.0-dev.2
setup.py	version	1.0.0dev2

This is a lot of spots where one needs to update this info. I can make something that models the preferred way of propagating this info into all the requisite spots. Just point me to what you want and I'll make a PR for it.

I'm not sure what's the best way of handling this. I suppose we could have the version stored and mutated in __version__, and then used in setup.py and in implementation_version. Then package.json could be updated from __version__ during a build step.

Understood, I'll look into best practices for a mixed language repo and pick one to use in a PR.
