While the related parser function sets the accumulated related pages as
extension data on the parser output
(see RelatedArticles\Hooks::onFuncRelated). The ParserClearState
handler, however, sets the empty list as a property, which is then
stored in the DB.
Changes:
* Make RelatedArticles\Hooks::onParserClearState use
ParserOutput#setExtensionData, mirroring ::onFuncRelated
* Add a unit test for the the handler

Since CustomData was written ParserOutput now supports the setting
and getting of properties. This patch switches RelatedArticles to use
that. I'm not sure if any other extensions depend on CustomData but
it seems to have served its purpose.

Add extension.json and populate it with information from both
RelatedArticles.php and the RelatedArticles extension wiki page [0].
Migrate the hook handlers to static functions operating on static data
rather than having a single, global instance of RelatedArticles so that
the hook handler definitions can be added to extension.json easily.
N.B. During testing the handlers for both the SkinBuildSidebar and
SkinTemplateToolboxEnd appeared to have the same effect so the TODO was
removed but not the handler for the former.
Additional changes include:
* RelatedArticles.class.php -> includes/RelatedArticles.php
* RelatedArticles -> RelatedArticles\Hooks
* Documenting all of the methods of RelatedArticles\Hooks
