What:
Add hook that runs after a save attempt is made in ApiVisualEditorEdit.
The hook receives the same data available in ApiVisualEditorEdit, and
implementations of the hook can modify the API response.
Also introduce templated
parameters (https://www.mediawiki.org/wiki/API:Templated_parameters) in
the API parameters; this allows plugins to pass arbitrary data along
with their request using e.g. plugins=linkrecommendation&data-linkrecommendation=foo
Add ServiceWiring files, a PHP namespace, and a HookRunner class to
support the above changes.
Why:
VE plugins may wish to send additional data when saving an edit and take
action based on that data on the server-side. See for example the
AddLink plugin in I7a052f8e which sends annotation data, and then uses
the new hook to perform a database operation.
