A fresh start

Due to Vanir being over 2 years old, some of a our more popular devices repos have become severaly bloated
In particular, Tuna has over 1.5 GB of prebuilt kernels.  This new path is a fresh start and just a few MB large.

You can see all of commits, suucesses, and failures here:
https://github.com/VanirAOSP/LEGACY_device_samsung_tuna

For very annoying technicalitites, git branch-filtering the kernels out was not a viable option.   Sorry for any inconvienance.
