Build v55 on Windows PART 2 (#294)...

There are still issues with unittests and examples. Tkinter example
launches fine, but crashes sometimes.

Update vcproj files and other fixes. Add additional linker flag
/LARGEADDRESSAWARE to Allow 32-bit processes to access 3GB of RAM.
Set UNICODE for subprocess.

Update build tools. Update module comments with great details
on how these tools work.

Refactor make-setup.py and make it work cross-platform (#299). Moved
to tools/installer/make.py .

Update docs.
Update requirements.txt.

Update tkinter example on Windows, doesn't support PNG images.
