More fixes for page includes: - Try in `/templates` first if the include URL is not absolute. - Fix problems with Jinja character conflicts by using their lexer. - Better pre-conditioning of include arguments in the formatter. - Optimize SQL queries a bit by deferring some properties. `manage update` can now update/re-cache a single page.
