Skeleton doismellburning module

(based on GDS standalone template so has a tonne of extras)
Skeleton XBMC role (purely nginx proxy for now)
Moved hiera-data over to hiera
Use newer Puppet (3.4.3ish)
Remove custom XBMC domain because of my local DNS fail :(
.gitkeep now obsolete as there exists data
Merge branch 'feature/doismellburning'

First actual bit of internal module work. Hacky, skeletal, but it's a start.
