Convert postprocessordirectives into preprocessordirectives, so they are
expanded before markdown. Consequences: - No need to worry about markdown messing with parameters of preprocessordirectives. (If you had to escape stuff in one before, you'll need to undo that escaping now.) - No need for ugly </p> hacks before inlined subpages. Instead, subpages are wrapped in a <div>, and this prevents markdown from touching them. (This can also be used to add style to subpages.) - rss generation is less of a hack.master

Done.. inlining is now a preprocessor directive, happens before

markdown, and the inlinepage template uses div as suggested, this does

prevent markdown from doing any annoying escaping of the preprocessor

directives, as well as preventing it wrapping subpages in <p>.
