Rolled out the Lablog-style Recursive Wiki Pages, which bring edit previews, edit history, file attachments, discussion, and child pages. Still some rough edges—they don't respect floatpics, making floatpics totally useless. (Not sure if a chapter can even find its floatpic without knowing its group?)

Also added Lects/Languages and Language Families. No more shoe-horning everything into wikis/chapters!
