updating to work with finalized dependencies
- updating Puppetfile (and refreshed .lock)
  to reflect released dependencies
- adding Modulefile (module name is tentative)
removing unused testing nodes (will probably add
some more later, at least for ubuntu 14.04)
adding misc. apache parameters support
- params are passed through to puppetlabs-apache
  module
- done to allow disabling Apache’s sendfile
  (which conflicts with vagrant-based “shared
  folder” setups)
