Hook up templating system to read the CHANGELOG for version and changelog info.
Modified nature.css to make it clearer on table headings/sub-headings. Use the
full _matrix/client path on title links to make it clear it is for v1.
Restructured the sections code to be slightly more encapsulated than before.
This will be expanded to more clearly separate the templating system from
the specific implementation of the spec templates.
* try to make 00_basis slightly more accessible and less terse
* move CS API before Events, as it's meaningless to dive into specific events if you haven't been introduced to how the CS API works
* Try to improve the beginning of the CS API by merging back in some of kegan's original v1 content (which has subsequently been deleted somewhere along the line?)
* document m.presence event consistently
* move typing from drafts to spec
* move push stuff from drafts to spec
...and lots of other stuff
move push & typing from drafts into main spec.
