Added a plugins directory and a PLUGIN contant for later use
- We need the plugin concept to exist (even if the path has to change later) so we can account for it in our MVC mapping
Added a constant for locating the tests directory
Added a mock up for the $_SERVER super global
Added a MockPlugin directory to aid with unit testing
- This is a technical deficit, I will refactor later
Removed obsolete concepts
Added a wrapper class for the $_SERVER super global
Added a class to assist with MVC mapping
