missing author firstname in ISI files

Pybliographer 1.2.6.2 fails to read the following ISI file:

FN ISI Export Format
VR 1.0
PT J
AU Mothe
TI Taratatsoin tsoin.
ER
EF

The reason seems to be the missing firstname in the AU field as shown
by the output of pybformat :

> mothe@zarbi:~$ pybformat test.isi
> pybformat: using style `Alpha', format `Text'
> Traceback (most recent call last):
> (...)
>   File "/usr/share/pybliographer/Pyblio/Format/isifile.py", line 163, in next
>     name, firstn = string.split (item, ',')
> ValueError: unpack list of wrong size

The following patch seems to fix the problem:
