	Japanese
	- Tmv

	TODO
	- Add support for mobile devices.
	- wrapContent is breaking the expand/collapse logic on the VFD page.
	- populate the input-type select list from LISTING_TEMPLATES
	- Allow syncing Wikipedia link back to Wikidata with wbsetsitelink
	- Allow hierarchy of preferred sources, rather than just one source, for Wikidata sync
		- E.g. get URL with language of work = english before any other language version if exists
		- E.g. get fall back to getting coordinate of headquarters if geographic coordinates unavailable. Prioritize getting coordinates of entrance before any other coordinates if all present
		- E.g. Can use multiple sources to fetch address
		- Figure out how to get this to upload properly

	 * CUSTOMIZATION INSTRUCTIONS:
	 *
	 * Different Wikivoyage language versions have different implementations of
	 * the listing template, so this module must be customized for each. The
	 * Config and Callbacks modules should be the
	 * ONLY code that requires customization - Core should be
	 * shared across all language versions. If for some reason the Core module
	 * must be modified, ideally the module should be modified for all language
	 * versions so that the code can stay in sync.
	 * ***********************************************************************/

	// see http://toddmotto.com/mastering-the-module-pattern/ for an overview
	// of the module design pattern being used in this gadget

	/* ***********************************************************************
	 * Config contains properties that will likely need to be
	 * modified for each Wikivoyage language version. Properties in this
	 * module will be referenced from the other ListingEditor modules.

		// the same parameters then a single configuration array is sufficient,
		// but if listing templates use different parameters or have different
		// rules about which parameters are required then the differences must

		// "checkout" in the "sleep" template, so a separate
		// SLEEP_TEMPLATE_PARAMETERS array has been created below to define the
		// different requirements for that listing template type.
		//
		// Once arrays of parameters are defined, the LISTING_TEMPLATES

		// types use the LISTING_TEMPLATE_PARAMETERS configuration EXCEPT for
		// "sleep" listings, which use the SLEEP_TEMPLATE_PARAMETERS
		// configuration.
		//

		//	- id: HTML input ID in the EDITOR_FORM_HTML for this element.
		//	- hideDivIfEmpty: id of a <div> in the EDITOR_FORM_HTML for this
		//	  element that should be hidden if the corresponding template
		//	  parameter has no value. For example, the "fax" field is
		//	  little-used and is not shown by default in the editor form if it
		//	  does not already have a value.
		//	- skipIfEmpty: Do not include the parameter in the wiki template
		//	  syntax that is saved to the article if the parameter has no
		//	  value. For example, the "image" tag is not included by default
		//	  in the listing template syntax unless it has a value.
		//	- newline: Append a newline after the parameter in the listing
		//	  template syntax when the article is saved.
