Comply with CakePHP Codinging Standards

There are some minor deviations from the CakePHP Coding Standards that I end up fixing each time I clone the project, to get the [CakePHP Code Sniffer](https://github.com/cakephp/cakephp-codesniffer) to pass successfully. I figured they should probably just be made to the master.

One note though; the three standard php files under app/Config/Schema also cause the sniffer to throw warnings due to missing documentation blocks but this isn't special to the app-template repo, its how CakePHP ships so I wasn't certain how to handle these three files (I usually delete them shortly after cloning). 

If it is desired to have a 100% pass right after cloning, I'm more than happy to add some documentation to the files and submit a new pull request.
