Made lensfun lookups for one lens really unique.  Fixes bug #9662.
Add keywords, as recommended here:

 http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s05.html,
 http://bugs.debian.org/693918, and
 https://wiki.gnome.org/Initiatives/GnomeGoals/DesktopFileKeywords
Proper english. 'allows one to', not 'allows to'
Keywords value MUST end with a semicolon
Use Exif.OlympusEq.LensType and give it precedence over
Exif.OlympusEq.LensModel and Exif.Photo.LensModel since it is normally
the most precise data and the string used in (the current svn of)
lensfun.

Italian translation updated
Add soft boundaries to bauhaus sliders

These have to be enabled using dt_bauhaus_slider_enable_soft_boundaries
and you should use dt_bauhaus_slider_set_soft instead of
dt_bauhaus_slider_set for those afterwards. Growing the region is only
done when entering the value manually (right click or vim keys).
Use soft boundaries of [-3 , 3] for exposure

Hard boundaries are still at [-18 , 18 ].
