Pascal approved

(cherry picked from commit d925fc1)

wb_presets: add Canon 760D

(cherry picked from commit 842546a)

disable mouse-over-image when no lua callback is registered

this should improve overall responsiveness quite a bit

this is a horrible hack which is OK in master but shouldn't
be ported to master. A whole rewrite of that area should
be done to fix this for real

Remove RELEASE_NOTES from release tarballs

That file isn't what users expect from a file with that name but just a
brainstorming/note dumping place for devs.

opencl: regard include files when checking for CL source re-compilation

earlier changes to include files (common.h, colorspace.cl) would not trigger
(re-)compilation of CL sources

translations: drop the ones with >= 10% untranslated strings

revert after release for the new master branch!

[l10n] Small update of German translation

Don't show image lib when lua adds a button

This made dt to always show the selected image[s] lib on startup, no
matter what's the expanded state.
