OctoPress was wonderful, but I need more low-level control over my site
and Octopress 2.0 is pretty outdated anyway.

Moved old site to _OldStuff
Added old octopress img tag plugin (to avoid breaking old posts)
Changed jekyll configuration to be more in line with modern standards
Added a Gemfile (and entry for .bundle in .gitignore)
Moved posts over to new site
Moved images over to new site
Moved some smaller files to new site (robots, keybase, atom.xml)
Added 'nil' layout option.
