Closes issue #21.

0b64bf0 introduced a hack (http://git.io/1ZbMkg) related to an issue
in bibtexparser : sciunto/python-bibtexparser/issues/17.
This has been fixed by sciunto/python-bibtexparser@6beb646 and the hack
can be safely removed.

Pubs should be updated accordingly as soon as the bibtexparser FIX gets to a released version.
