Proposed spec for Parsoid's gallery implementation

	<!--

	Working off: https://github.com/wikimedia/mediawiki/blob/master/includes/parser/Parser.php#L5300-L5312

	Params to support (on the extension tag): showfilename, caption, mode, widths, heights, perrow
	Content is explode by: \n
	A line should match: "/^([^\|]+)(\\\|(.*))?$/"

	If a '%' is found, rawurldecode?

	Title is before the first \| and needs a namespace: NS_FILE

	TODO: Mainly the "mode"s, and their interaction with "widths", "heights", and "perrow".

	-->

	<gallery caption="Foo [[Main Page]]">
	[[x\|xx]]]]
	File:Nonexistent.jpg\|caption
	Image:foobar.jpg\|some '''caption''' [[Main Page]]
