Update docs.md

Fixed a minor spelling mistake
Bind quiescent/*component* when calling on-initial-render callback fn
Rename `on-initial-render` to `on-mount` for clarity
Added more lifecycle wrappers...

The `componentWillMount` and `componentWillUpdate` are helpful if you
need to setup/cleanup event handlers outside of React. An example would
be a component that listens for history events to do some routing. Or a
component that listens for key events on the document or window object
to hide or show a modal dialog.
upgrade to ReactJS 0.9.0
Property maps are now parsed to JS objects recursively

This means that styles can be specified as Clojure maps.
Correct Article component
docs.md: Fix some typos.
docs.md: Note Quiescent now available on CLojars.

Not sure if this is the best wording.
Added `componentWillUpdate` lifecycle wrapper...

Adds the `on-will-update` and `on-will-render` lifecycle wrapper fn's.
These can be used to prepare the page for an update, e.g. by adding or
removing a class to trigger an animation.
Fixed missing paren
