Cleaned up the formatting, removed hard path references (the default installation of Node.js includes these tools in your path), and replaced node.exe with CALL which executes the command while continuing to process the script.

Fixed bug in COPY command where combined file was picking up a junk character at the end, and added responsive.less to the build (also renamed it)
