OpenAtlas

When uploading and linking multiple files to a reference, it is not possible to add a page number directly, so it has to be done individually afterwards. This could be quite cumbersome e.g. when entering multiple images from a catalogue where there can be many images on one page.
To make it more efficient, we could add the page number field directly when adding and linking a reference. We can implement this also for adding references from other entities like e.g. actor which will save a few clicks when entering data.

Update
If files are added through a reference, the page input field is visible in the file upload form and the between page is not needed any more. The entered page will be added to all uploaded files.
