Began work on Environment save code.

Restructured the project save data folder layout when the engine starts.
The XMLData class now creates directories if they are missing.  Individual classes no longer need to check if a path is valid before saving.
Filenames are now automatically generated and no longer assigned by developers.  This change has been made across all classes that are savable which required some changing of the Save() method arguments.
