* Add test for raw bibtex entries on the details page. It currently fails as the details generator does not get passed through the liquidify utility, but instead is passed to liquid parser immediately.

* Fix the issue that the bibliography tag is rendered differently on the details page than in the bibliography tag. They should now behave (more or less) in the same way.

Take into account source directory from original configuration for the generated repository links (#152)

* Allow the test environment to keep the originally sat 'source' value.

* Add a test case and a fix for the ignored source setting in the configuration file.

* Prepend the TEST_DIR only when the source configuration is not set to an absolute path (making it absolute in the process)

* Fix the definition of the relative repository paths, and fix the test feature to properly use the configured source directory.

 * Add group_by option, to group bibliography entries.
 * Add proper names for entry types, and months.

Added a note in the documentation on the usage of this option.

This simple 'solution' returns all entries for ``--max 0``.  Now, to
avoid this the logic of ``offset`` and ``max`` needs to become more
complex - unless I am missing an obvious solution.
