#96 Frontend tooling

@andrewmallis @robLoach @gremy @reynoldsalec @madeofpeople 

Here is a good starting point to standardize our front end toolkit in Kalastack. This is a short term thing for immediate needs. A better solution will be created for KB2 using docker and other deeper magics. 

I need people to QA this pull request to make sure it is consistent and integrates with our current workflows. In practical terms we just want to make sure the versions of all the things here are appropriate.
