Added README.markdown. Didn't add yaml front matter
because I'm not sure how git would react, and that's the
reason I added it. Linking it as my About page because markdown
is not difficult to read as plain text.

Updated CNAME.
fixup! Updated license to be non-commercial
Added shell script for deployment _deploy.sh

Created _deploy directory, because jekyll deletes .git
every time I generate the site.

Added _deploy to .gitignore.

Wrote a shell script that deletes contents of _deploy
and copies _site into _deploy.
Added categories journal and archive.
Some css, pagination and aesthetic changes
