Subject: [PATCH 3/3] EPUBHTMLManager: fix value of <navPoint playOrder"...">

<http://www.niso.org/workrooms/daisy/Z39-86-2005.html#NCXplay> "8.4.3
playOrder Attribute" says:

	playOrder is a positive integer; the first playOrder value in a document
	shall be 1.

So instead of writing an empty attribute, write the same number that's
already used for <navPoint id="...">.
