Refresh Gyp MSVS files, including patch for Gyp bug #377

Working on getting Visual Studio 2013 compatible with v8, node, gyp, and node-gyp.  Seeing many compatibility issues reported on our library node-serialport.

This patch includes an update to the latest Gyp MSVS files which have a number of small compatibility fixes.  It also includes a patch to be compatible with VS 2013 express which is not yet merged into Gyp.
