natty: remove files because Ubuntu dropped it from their archives

No point in maintaining these files because the Launchpad PPA does not allow
for uploading. Support was ended on 28 October 2012.
lopq/bbswitch: update to 0.5
Added Raring Ringtail packaging scripts (copied from Quantal Quetzal)
Added raring to helpers

opqr/bumblebee-nvidia: Relaxed nvidia-current version dependency
lopqr/bumblebee: auto-detect nvidia paths in initscript
lopqr/bumblebee: remove superfluous patches

- 006-set-vgl-readback-pbo: merged with 3.1
- 007-nvidia-fallback-probe: using initscript. Consequence: manually starting
  with bumblebeed may fail to detect the correct nvidia driver. Anyway, the
  ModulePath was not set so this patch was broken already.

lopqr/bumblebee: set --driver-module, allow /usr/lib/nvidia/
lopqr/bumblebee: test nvidia kernel module, set driver to nvidia
lopqr/bumblebee: Added nvidia-313 blacklist
