Build zqcc on Windows

* Updated build files to reference the MFC lib (fixes the afxres.h
problem, as we did with ZQuke).
* The solution files were updated to VS2013 Express (may work on 2012?).
* Updated BUILD instructions to clarify that we've already made changes
to the project files so only installing the DDK should be needed (needs
further work; too wordy for users right now).
* Be sure to ignore the (hopefully) correct zqcc VS/build files.
