Iptcinfo3

1.9.5-7: https://bitbucket.org/gthomas/iptcinfo/issue/3/images-w-o-iptc-data-should-not-log-errors - have silencable parse errors.

1.9.5-6: to have a nice new upload (seems easy_install grabs an old version).

1.9.5-3: use logging module.

Also a new (mis)feature is implemented: if you don't specify inp_charset
(and the image misses such information, too) than no conversion is made
to unicode, everything stays bytestring!
This way you don't need to deal with charsets, BUT it is your risk to make
the modifications with the SAME charset as it is in the image!

charset recognition loosened (failed with some image out of
Adobe Lightroom).
