Function Mocker new version almost ready

Developer version of Function Mocker is live and working.

##Developer preview
I’ve gone over the new features that function-mocker will sport and am not repeating myself.
The develop branch has them all minus an updated readme file.

I will go over that next and resume working on the Etsy sync plugin and the additional CMB2 fields I’ve put aside to work on the function mocker iteration.

I appreciate your input
