Merge the Layout and Design tabs into one form with a single Save

The look and the layout of a blog were split over two tabs that cross-linked
each other, and the Layout tab saved every toggle, move and add straight
away through a dozen tiny forms. Now one Design tab holds it all, organised
by part of the blog (colours & fonts, header, menu, content, side columns,
footer, logo & icon) behind a sticky side index, and one Save stores the
theme, every module and the menu atomically (BlogStore.SaveDesign). Module
settings are edited inline; Discard changes throws the edits away; a
validation error shows the form again exactly as it was sent.

The image pickers no longer render the whole library four times over: a
select of the newest images, and a script-driven panel that fetches the
library page by page (GET /files as JSON) with lazy thumbnails.

New options: posts per page, site title size, footer alignment.
