This commit separates the files wiki2jax.js and texvc.js from the MathJax modules. This allows for MathJax updates without affecting MediaWiki files. It also defines the MediaWiki path configuration, although this will really only be usable in MathJax 2.4. Finally, it fixes jshint errors in texvc.js and wiki2jax.js Moved texvc.js and wiki2jax.js to extensions/Math/modules/mediawiki-extensions directory Change-Id: I97d68c0555bc9fbdd6bf42912aa249d57b3d9359
