Fresh drivers from upstream, currently shipping Nvidia.

## Current Status

We currently recommend: nvidia−361nvidia-361, Nvidia’s current long lived branch. 
For GeForce 8 and 9 series GPUs use nvidia−340nvidia-340 
For GeForce 6 and 7 series GPUs use nvidia−304nvidia-304

## What we’re working on right now:

– Normal driver updates– Investigating how to bring this goodness to distro on a cadence.

## WARNINGS:

This PPA is currently in testing, you should be experienced with packaging before you dive in here. Give us a few days to sort out the kinks.

Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/
