Fixes RSS issues. Changes time tracking to git

This commit primarily changes the code base to base the file last
modified time on the output of "git log". This adds dateutil and git
itself as a dependency, but those are pretty common...

This also fixes some minor issues including:

- missing / between mjfer.net and the URI
- README up to date with latest changes
- linting
