* 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.
