recording app: hide dummy images in the remaining image lists

[urapadmin]

see #2409:

• unless "show_dummy_image_rows" isn't explicitly set to "yup" dummy images in image lists will be hidden if
  • they don't have a description in the displaying context
  • you are in dayplans, site notes photos, locus photos or collected material photos
• all those lists show the number of available images in the lists somewhere. dayplans and site notes in a heading, locus photos and collected material with the images. Those numbers are off because they count all images and not only the visible. I am currently not sure what to do about it. In a way I even like that one gets a hint that there is more than meets the eye but on the other hand the numbers differ for no apparent reason from what one sees. In the current version I leave it at that and make a new ticket for it: #2410

This is about the remaining image lists. Apparently I had only implemented it for a few of them, Not entirely clear which ones.
