Title: bibtex and autobib can fail when missing author fields.

* Changed bibtex author parsing to handle missing author field.
* Changed cite in autobib to handle missing author field.

I noticed this problem when trying to do ```@~cite["paper" "misc1" "misc2"]``` when ```misc1``` and ```misc2``` did not have an author field.
