Special pages: a gallery page of the blog's images

A page's kind says what it shows between its intro and outro: posts,
as before, or something special. The first special kind is a gallery —
every image in the files library as a masonry wall (CSS columns, no
script), newest first, each linked to its full-size file. The page form
lists the library's images with a Hide tick per picture; exclusions are
stored (page_hidden_files) rather than inclusions so a new upload shows
up without editing the page, and the design's own pictures — logo,
favicon, header and background image — are never shown. Special pages
keep the page chrome (menu, announcements, home, ordering) but hold no
posts: the post forms skip them and a forced page id is refused.
