add inclusion comments



sometimes want information on forms, layouts, etc that doesn't get exposed to users


  -- nothing gets rendered at all

-- renders as an html comment, eg <!-- # visible comment -->



I did this when I was refactoring the inclusion expansion for the new layout system and forgot to mention it.  -e

Seems fine. Rather idiosyncratic, but i can't think (in 30 seconds of pondering) of another way to do it that's better. Closed and documented (on nesting).
