	/**
	 * Add reference insertion tools from on-wiki data.
	 *
	 * By adding a definition in JSON to MediaWiki:Visualeditor-cite-tool-definition, the cite menu can
	 * be populated with tools that create refrences containing a specific templates. The content of the
	 * definition should be an array containing a series of objects, one for each tool. Each object must
	 * contain a `name`, `icon` and `template` property. An optional `title` property can also be used
	 * to define the tool title in plain text. The `name` property is a unique identifier for the tool,
	 * and also provides a fallback title for the tool by being transformed into a message key. The name
	 * is prefixed with `visualeditor-cite-tool-name-`, and messages can be defined on Wiki. Some common
	 * messages are pre-defined for tool names such as `web`, `book`, `news` and `journal`.
	 *
	 * Example:
	 * [ { "name": "web", "icon": "ref-cite-web", "template": "Cite web" }, ... ]
