Add: Grunt wrapper for Jekyll; Mod: Folder structure; Mod: index.md; Add/Mod: talentbrew/index.md

Adds a Grunt wrapper around the Jekyll build for livereloading and proper SASS preprocessing. Grunt replaces Jekyll for SASS preprocessing.

Modified the folder structure to be more clean and concise.

Updated index.md with new information, as well as modified sections.

Moved the talentbrew-specific page to its own folder so it's easier to access and to hide the .html extension in the URL.
