Tools and Technology Standards

Please add notes of the standard tools/technologies that we have accepted and recommend for use at edX.  
For example, do we think that they are Backbone, JS, Python, etc… Apiary, Jenkins, DBs, App Servers, etc…

If we have legacy technology we are using, we can note it, but we should make it clear that it's not a recommended standard.
