gave adinebook priority over ottobib for isbns +support Farsi ISBNs

# now when an ISBN is given, program checks adinebook before ottobib
# only 'adinebook.com/gp/product/' is considered a valid adinebook url
# the was a problem when logging URLs. url.decode('utf-8') was added.
# convertors was renamed to conv
# if no title is found in adinebook then it's assumed the page does not
    contain book information
# fixed a minor bug when adding the name of multiple translators in
    fawikicite.py
decided that 'others' won't be added to final citation

Although it's very easy to add them, but I feel it's just a try to fill
citation parameters without considering their value. If requested it may be
added in the future.
added test module test.py ++

# now Noormags uses both bibtex and RIS to obtain all and correct infos
# combined the way journal and book citations were created (nothing tha
	normal users will notice)
# and other minor improvements
