[l10n] Update of German translation
usermanual: proofreading chapter 3 "color group" thanks to Rob Z. Smith
Merge branch 'master' of ssh://github.com/darktable-org/darktable
usermanual: another fix in base curve
Update Spanish translation
usermanual: almost final for 1.2
update of dutch translations

noise profile: set combo box to empty in case you copy/pasted from another camera
colortransfer: removed unnecessary color picker event.
colorout: hide/unhide rendering intent controls according to preferences

this hides or unhides the rendering intent controls after each run of
pixelpipe if needed. there is still no immediate reaction on a change of
the lcms2 configuration parameter; at least the GUI now updates faster
than before.
Workaround for libgphoto2 API breakage in 2.5.0. Fixes red hat bug #892228.
