jekyll is NOT an NPM package: `npm install` barfed a hairball on that one -- it should exist in the gemfile only!
add _gh_pages as submodule so we can easily update the gh-pages branch on each `jekyll build` run
enforce policy to have all text files in UNIX (LF-only) format, irrespective of the platform/rig used to do development at any time.
added a root Makefile: `make` builds all files that accompany Font-Awesome and are turned into the website for the same.
Note: src/Makefile is already executed by `jekyll build` itself, so no need to run it again in the root Makefile.
