Renamed the main sls file to debian_full

This is a great and full-featured way to configure Apache on
Debian-family OS's but we need a simpler and more universal formula as
the main entry-point.
Added basic formula to install Apache
Updated Debian-family formula to use main sls but keep custom ordering
Updated Debian-family formula to work on all Debian-family OSes
Updated README with these changes moved Pillar examples into pillar file
Merge branch 'generic-apache'
