Remove the manifest php55 and replace with more flexible apt

The php55 manifest is a hacked together version of what the apt package is.
The apt package adds flexibility and allows you to define multiple apt repositories
to add simultaneously.

Fix for apt manifest multiple repositories

Add the $name variable to the exec. Puppet requires unique names for each class.
This allows you to add multiple repos to be added sequentially.
Add node.js base manifest for value

Adds a node.js base manifest. You can specify the manifest using the environment
variable MANIFEST. You must set the MANIFEST environment variable before running vagrant.
Default is to run the phpbase.pp.

On Windows use:
SET MANIFEST=nodejsbase.pp
vagrant up

On Mac or Linux you can do it on the same line:
SET MANIFEST=nodejsbase.pp vagrant up
