Addition of xdebug and MailHog modules

Documentation has been added, xdebug and MailHog modules added and enabled

Puppet Restructure and Cleanup

Puppet code has been greatly cleaned up and simplified. The puppet-mysql module is now in use for managing and seeding the database.

puppet-apache was attempted to be used, however the current apache site configurations are bloated with so much customization that it is very unclear what is required and what is not. It makes more sense at this point to simply use the existing site configuration rather than convert it into a puppet-apache friendly configuration, as putting in that effort will not have much reward in terms of working better or reducing complexity.

Planned additions will be creating a hubzero-mailhog and hubzero-xdebug module, and adding Vagrant configuration to support using these tools easily.

Initial Release

Configuration is fully working and automated to get a CMS running for testing.

Future releases may include restructured and improved Puppet architecture, Mailhog configuration, and Xdebug configuration.
