[DO NOT MERGE YET] Update fro Jedi.el v0.2.0

These are the changes required to install new version of Jedi.el

I am planning to merge this just before pulling this (i.e., "releasing" v.0.2.x):
https://github.com/tkf/emacs-jedi/pull/72

Since I was away from el-get dev for a while, I thought it's better to give other devs to have a look.  But these recipes are working locally in my Emacs setup in two computers, and test-recipe.sh says nothing, I assume  it is fairly safe to pull it anyway.
