wb_presets: Sony SLT-A58 (fixed)
blending: fix recent warning message 'unknown blend mode 0'
Merge branch 'master' of ssh://github.com/darktable-org/darktable
Slightly change dt_develop_blend_params_is_all_zero

no need to keep iterating if we already know the answer
blending: partly revert commit 21a9f06732746023da827e8061afec2dbab9aa15 with a better solution
remove dt_film_import_blocking

it was lying about what it was doing, this does not change the fact that the lua API is not working like expected, but it works like it used to, so  fix in another commit

also fix DT_SIGNAL_FILMROLLS_IMPORTED not being triggered at the right time
lua : add film handling

darktable.films : pseudo table of films

film.id  : the film's id
film.path : the film's path
film.# : images belonging to that film

image.film : the associated film object
lua : new event post-import-film

trigered when a film has finished import.

one extra parameter : the film that was imported
lua : make database.import return usefull information

when imorting an image : the image that has been imported

when importing a directory : the film that is imported

note that the function returns immediately, so when importing a film, the object is correct but the images havn't been imorted yet

use the post-import-film event to find out when import is done

and darktable will display the contents of a text file with the same name
as your image but .txt suffix as on overlay in one-image-per-row mode.
