Using Tags Instead of Stable Branch

[robelgeda]

Right now we use the sable branch for mybinder builds. I noticed that you can use git tags to specify the commits (the history) you would like to build in mybinder. Adding a tag on GitHub is like doing a versioned release of the code. This is a better way of keeping track of changes as well as keeping mybinder builds at sable points.

This sounds like it would be a solid improvement in workflow to me. @ariedel, do you agree?

Yes, this seems like an excellent way to keep stable versions around.

Sounds like a plan!
