A different approach to apache::mod::passenger

Note: this requires
huit/puppetlabs-apache@034d018b562e1dce3f6aea4018ba085a0800b03c to be

mod_libdir_package_params branch.
Merge branch 'puppetlabs_apache' into cloudlet-railsapp

Conflicts:
	manifests/passenger/apache.pp
Oops, forgot to build the Apache module!
Merge branch 'puppetlabs_apache' into cloudlet-railsapp

Bugfix - forgot to build the Apache module
Install apache::dev
