Route handling and rendering for "full" author pages.

[crudbetter]

Additional features/modifications to the excellent Wheat blogging engine that attempt to make it an equally compelling option for personal blog sites as it is for community blog sites.

• Add additional route handling and rendering for full author pages. -Allow authors to further promote themselves by optionally specifying lists of languages, tools and interests - implemented as headers in author markdown documents and delimited by ";".
• Make category display case insensitive.

For an example of a full author page please see http://godders83.com/author/Mike-Godfrey.

Hi creationix, Wheat is the first project on Github I have successfully forked and made changes too. So this is also my first pull request - hope I've done it all correctly and you have time to review it in amongst all your commitments to JsGit. Many thanks, Mike Godfrey.
