Trying to get away with returning a single code and parameter-list that
was supposed to represent both human-readable and machine-readable data
was a mistake.
This patch converts it to use DataMessageValue, which represents the two
separately and also provides guidance for supplying translations of all
the error codes.
This also eliminates the "describeSettings()" method that was trying to
serve multiple use cases (in terms of the Action API, action=paraminfo
and action=help). It's replaced by two methods that each serve one of
the use cases. Also some of the functionality was moved out of the
TypeDef base class into ParamValidator, to better match where the
constants themselves live.
Also I wound up creating a NumericDef base class so FloatDef can share
the same range-checking logic that IntegerDef has. I probably should
have done that as a separate patch, but untangling it now would be too
much work.

* Add ResponseFactory::createLocalizedHttpError(), which generates a
JSON response body from a MessageValue
* ResponseFactory::__construct() accepts an array of TextFormatter
objects. For ease of testing, the array may be empty. The integrated
ResponseFactory has a TextFormatter for English, and one for
$wgContLang if that is different.
* Use createLocalizedHttpError() to show helpful error messages for
errors generated by Router.

An injectable service interface for message formatting, somewhat
narrowed compared to Message.
Only the text format is implemented in this framework so far, with
getTextFormatter() returning a formatter that converts to the text
format. Other formatters could be added to MessageFormatterFactory.
