Implemented new Pages plugin

Added pages.rb (created by Ben Baker-Smith (https://github.com/bbakersmith/jekyll-pages-directory)) to allow me to hide all my pages inside a directory
Moved about.md and archive.html into the new _pages folder
Merge branch 'source' of github.com:richardp2/richardp2.github.io into source

Conflicts:
	_pages/about.md
	_pages/archives.html
