Fixed link behavior.

* Removed the automatic document table heading based on the document id.
* Fixed the way 'absolute' links were resolved in `Processor`. A leading `/` for
  a link passed into `Processor.resolveLink` really means "resolve as if I am
  starting from the documentation root."
* Moved the default logging configuration out of the final jar path. This is to
  help with environments that have multiple projects in the same classpath and
  therefore may have multiple `logback.groovy` configurations loading.
* Tweaked CSS.

+Automatically create document `org` directives.
+===============================================
+
+The author should not have to create an `org` directive at the top of every file.
+This should be done for him during parsing. Ideally the system would be smart enough
+to notice if he has defined an `org` at the top of a file and use that if he has.

+Add a `title` directive for titling documents.
+==============================================
+
+Return to defaulting a title for each document. Instead of the internal document id use
+something more reasonable, like the filename without the path and without the extension.
+A new attribute `title` could allow the author to override this value.
