[css3-layout] Added some more properties that apply to ::slot(). Added
that slots rotate depending on 'writing-mode', but the grid itself
does not.

[css-module] Removed the unusual parenthesized part from the TITLE
element. Used the new [TITLE] macro to avoid hand-editing in the
conformance section. Gave the document a syntactically valid shortname
(css-module). Updated the URL for the bibliography database.
Added some rules from the Makefile in ../css3-layout
Generated. Do not edit!
