Pick images, pages, forms, sections and terms instead of typing ids and addresses

The share image and featured image of a page become image fields with the library dialog,
as do image settings of plugins. The editor offers forms, sections, categories and tags as
lists, a page search next to every link target and in text links, the redirect target has a
page search, and the form editor picks the reply field, the condition and the option images.
