Ignore _site directory.
Added sitemap_generator plugin.
Major changes to incorporate Jekyll.

- Extracted index.html into default template.
- Applied default template to home, about, effective-d.
- Removed JS navbar solution.
- Altered footer text.
Renamed font file.
Added Sublime Text project.
Made CSS more readable.
Refactored index to Markdown, extracted links.md.

I figured that all those links deserved their own page.
Removed About and Effective Design pages.

The about page was mostly necessary for my web design class, and most
of its content is already on the homepage.

Effective Design is a good idea, but it's dead for now.
Writing changes.
Merged _site from Jekyll prep branch.
