Changed overlay name

The overlay will now contain all environments (staging and production) organized 
using categories
Moved hackbytes source ebuild to ebuilds directory.

This directory will contain source ebuilds and is the only place where ebuilds 
can be modified. The category directories will contain generated ebuilds created 
by the build server.
Moved hackbytes ebuild into it's own directory.
generated ebuild for puppet-nitelite-62

Added puppet-nitelite ebuild

added slot value. without it, ebuild breaks

Updated source var so that it does not have the environment type defined.
The directory packaged in the tarball does not have the environment defined
and the ebuild expects the source var to match the directory name. Otherwise
the ebuild will fail during installation.
