Updates move pagination to work with pretty URLs.

Pagination for the moves list on single Ivanhoe games should now work with both
pretty URLs and the default URLs. This adds a rewrite rule to account for the
page query variable, and overrides WordPress's default URL redirection so the
/page/[num] remains in the URL when clicking pagination links.
Adds default sass goodies.
Use path to Sass-generated CSS file.
Preliminary conversion to Sass syntax.
Adds borked Susy stuff.
Adds Gemfile for bundler
Add a gemset
commits for susy
