Changed test2.bbl after fixing a bug in 'citelabel' definition.
Removed generate_bibitem_label() as unnecessary.\n\nThis also gets rid of what has been a duplicate pass through defining the 'citelabel' special variable, and so should speed things up a little.
Substantial changes to test7 in bibulous_test.py.\n\nThe structure of the test had to change as a result of removing the n'generate_bibitem_label()' function inside bibulous.py.
Modifications to test7 in testing suite as a result of changes to 'citelabel' definitions inside bibulous.py.
