Factored all date formatter caching into a separate category, and made the category use NSCache.
Updated the default template files to work correctly with the latest version of GRMustache. Progress marches on!
Made sure that the posts file watcher *always* gets set up and started.
Fixed the date format string for the post display dates.
Removed an old reference to a nonexistent document controller subclass.
Removed all @synthesize lines! Hooray!
