first attempt at atom feed
added another author John DOe to test out post signing
More todos
added 'new_post' option (from octopress)
added tags and categories tasks to genrate tags and categories pages
tweak font sizes to be a little better for the tag/category clouds
added `rake author` to list posts by a particular author
pretty URLs
generate year/ and month/ indices
Merge branch 'rakefile' into skellington (tag/category/date indices
generated by rakefile)
rake generate to do tags, authors, categories, years and months
added year/date searches to the sidebar
added author search and workaround since handleize seems to be not implemented
