* doc/sane-mustek_pp.man, doc/descriptions/mustek_pp.desc,
backend/mustek_pp*: replaced the old mustek_pp backend with
version 12-alpha. This version fully supports CIS scanners but
removes support for 600dpi CCD scanners and the 300dpi CCD
support isn't yet working. In contrary to the old backend, this
version is based on information provided by Mustek. For now,
the backend exports lots of illegal symbols, this will be fixed
before code freeze. Also the .desc file is empty and will be updated
soon.
* AUTHORS: added Eddy De Greef who wrote the CIS hardware driver part
