PhantomJS runner files, allowing use of HTMLCS on the command line.
Requires PhantomJS to be downloaded (phantomjs.org) and installed in the path (eg. /usr/local/bin).

Usage: phantomjs ./PhantomJS/HTMLCS_Run.js [URL] [StandardCode]
Where StandardCode is the folder name in the Standards directory, eg. "WCAG2AA".
Currently gives a pipe-separated list of error level, code and message, one per line.
Error level is 1 for ERROR, 2 for WARNING, 3 for NOTICE. This will probably be cleaned up in later commits.
Replace level 1,2,3 with ERROR, WARNING, NOTICE.
