incorrect name parsing

[Former user]

Name formatting/parsing is incorrect (different from bibtex)

example: author = "Johansen Kyle, Derik Mamania M. "

"Johansen Kyle" should be surname, but pybtex formats it as a prefix (person.prelast)

bibtex names formatting algorithm http://www.tug.org/TUGboat/Articles/tb27-2/tb87hufflen.pdf

(ps: I'm sure there's no man on the earth with such a name :D)
