Add prototype projects page, data file.

_data/projects.yml
	-Add a Jekyll data file to contain all project information.
	-Will populate `projects/index.html`.

projects/index.html
	-Add a rough projects page, with a decent amount of markup and
	structure.
Add foundation projects page stylesheet.

css/projects.sass
	-Add a baseline stylesheet for the projects page.
	-Give the page a general layout, and some more specific styling.
Add projects item to header/home menu.

_includes/header.html, css/header.sass, index.html
	-Add a link to the new projects page.
Fix awesome fonts loading issue.

_sass/_mixins.sass, css/about.sass
	-The custom awesome font wouldn't render correctly on the about
	page in some browsers: issue due to incorrect bulletproof font
	syntax.
Refactor fonts dir organization.

fonts/(social_media_icons.* > social_media/social_media.*)
	-Move the different font formats for the `social_media_icons`
	set into their own directory, `social_media/` (also, rename each
	file root to `social_media`).
	-This structure will be adopted for fonts added in the future,
	for a much cleaner `fonts/` directory.

_sass/_mixins.sass
	-Modify the `font()` mixin accordingly.
Rewrite font() to take a single argument.

_sass/_mixins.sass
	-For brevity's sake, rewrite `font()` to apply the font files'
	base name as the font's `family-name`: now only requires one
	argument.
Finish styling projects page; add images/fonts.

projects/index.html, css/projects.sass
	-Finish styling/structuring projects page.
	-Add github/download links.

fonts/projects/*, img/projects/bitshift/*
	-Add projects page resource files: a custom awesome fonts
	package for link icons, and a sample image for the only project
	currently displayed (will be changed.)
Add real data for several projects.

_data/projects.yml
	-Add real entries for several of my past projects.
Minor layout styling changes to projects page.

_sass/_variables.sass, css/projects.sass, projects/index.html
	-Wrap all projects in a separate `div`, and some
	`padding`/`margin` rules.
s/    /  /g in _config.yml for consistency.

_config.yml
	-`yaml` files should have two, and not four, space indents.
Remove images from projects page; mod CSS/layout.

css/projects.sass, projects/index.html
	-Remove images from the projects page because the only valuable
	ones, in most cases, would've only been GIFs, which are far too
	large collectively.
	-Remove `img` element from HTML and relevant style rules.
	-Huge diffs caused by removal of the now superfluous `div.text`,
	which wrapped all text, and the resulting de-indentation for
	consistency.
Remove img links in _data/projects.yml.

_data/projects.yml
	-Following up on fc9a61e, remove all projects data entries'
	`img` values.
Add optional hyperlink button to projects.

	entry.
