Fixing project names to fix VS bugs

For whatever reason, Visual Studio throws a fit if a referenced project has a name
and the folder name (which is used to reference the project) is different than that name.
To solve this issue, I've renamed all the projects and folders to match their project
names as stated in the project.json.
