Add Feature to Mezzy to Guide installation of Mezzanine Dependencies.

[Sqeaky]

It is easy to setup the Mezzanine dependencies for an experienced developer, but many interested in game development are interested in game development are less experienced and setting up a development environment can be challenging.

This feature should walk a potential game developer through at least the following steps:

1. Setting the MEZZ_PACKAGE_DIR in the environment.
2. Installing CMake,
3. Installing Git,
4. Installing a Compiler,
5. Potentially installing an IDE,
6. Building the Mezzanine,
7. Building the Docs.
8. Creating a new package that does something like "Hello World",

Test this with @hlayne35, their knowledge is perfect to see if this works.
