3akai-ux, Etherpad-lite and Hilary are now installable via an Ubuntu package.
Added all dse dependencies.
Split out installs for etherpad and hilary
into a git and apt subclass.
Performance and QA environment should use git to pull down their sources.
Merge pull request #19 from simong/packed-hilary-3akai-ux

Added the ability to use the packed versions of 3akai-ux, etherpad or Hilary
Merge branch 'master' into nginx-multihost-vagrant

* Changed 'require' in ::oaeservice::hilary
  ** avoids establishing unnecessary dependencies
* included ::ui directly in ::oaeservice::hilary since it is assuming it exists with an ordering

Conflicts:
	modules/oaeservice/manifests/hilary.pp
Release ordering from oaeservice classes, add defaults for source/package install properties
