A couple stray changes
Standardizing spacing in SCSS
Adding project pages, refatoring a whole lot

Project pages are now defined by a YAML and Markdown file
projectpage.php renders each page, with an assist from mod_rewrite
It's purpose-built and simple, and I like it.

Of note:
 - Added composer, to get Markdown parser in
 - Added images and files for three projects
 - Tweaked some htaccess to fix some fiddly bits
 - Altered some styles, notably added brackets around links
 - Moved projects.php to projects/index.php
