Directory Structure Overhaul

Restructuring the directories, for easier workflow.

Visual Studio solution provided in its own folder. Note: If you plan on
modifying the branch, please provide detailed information on changes and
file locations so visual studio users can easily readjust.

The Visual Studio solution uses $(OutDir) for its working directory,
meaning it looks there first for image files.

If it's not too much trouble, please put new images and audio files in
the Release / Debug folders that are located inside the Visual Studio
folder. This helps out a lot. If you create any new headers (hpp) or
object (cpp) files, please move them into the /Ball Game/ folder located
inside the Visual Studio folder, as well.
