Added relativeCreated to Formatter doc (has been in the system for a long time - was unaccountably left out of the docs and not noticed until now).
Documentation clarified to mention optional parameters.
Documentation omitted the additional parameter to LogRecord.__init__ which was added in 2.5. (See SF #1569622).
