XBMC Packaging Repository

Clones the XBMC repository and prepares builds for upload to a ppa.

TODO:
  -Install proper exclude filters for source generation
  -Massive cleanup of the debian/ files
   
Notes:

By default, xbmc-get-orig-source will clone mainline xbmc into the xbmc/
folder in the repo root. Because this is a .gitignore'd git repository
it will _not_ be removed with a git clean -xfd. This means that we can
wipe with each build while avoiding a reclone.
  
If you have a local xbmc git clone already, you may use that path rather
than xbmc/. See the XBMC_SOURCE variable. With this configuration,
xbmc-get-orig-source will checkout files from your local repo into its
working directory, so there is no need to keep 2 clones. Your 'origin'
remote _will_ be updated, otherwise your local clone is read-only.
