Bugfix release

Fix two typos that'd break usage.

New release

• allow passing through latexdiff options
• include a clean command to quickly remove the temporary branches that Zaphod creates.

Updated to use latexmk

We now make advantage of latexmk!

Improved error checking

• Check pdflatex output for errors (quite common when you're using advanced LaTeX constructs)
• other minor changes and fixes

New zaphod release

• Permit partial file reviews
• Better interface and outputs
• Strip preamble only if none of the source files have any more latexdiff annotations

Further enhancements

• let user specify a git message
• let user decide if they want to generate pdf or not
• let user pick what file they want to edit
• let user edit only some of the files
• other various improvements

Nice and tidy

Since releases and tags are different on Github, let's create a new release!
