Pages that lay out the way they should

Another pass of putting Floati next to the reference browser on real pages and fixing what did not line up, all about how pages arrange themselves. The biggest win is documentation sites: pages like a developer-docs site that place a navigation column, the article, and a table of contents side by side were collapsing into a single stacked column, and they now lay out as the three columns the reference browser shows. Two more layout fixes came out of the same sweep. A box that floats beside an article and sizes itself to its own contents (a database project's "Common Links" panel, for example) was expanding to fill the whole width and squeezing the article text down to one word per line; it now takes only the room it needs. And small joined phrases, like a date written "July 16" or the dot separators in the encyclopedia's navigation boxes, no longer break awkwardly across two lines.
