	Returns the $qa_content structure for a question list page showing $questions retrieved from the
	database. If $pagesize is not null, it sets the max number of questions to display. If $count is
	not null, pagination is determined by $start and $count. The page title is $sometitle unless
	there are no questions shown, in which case it's $nonetitle. $navcategories should contain the
	categories retrived from the database using qa_db_category_nav_selectspec(...) for $categoryid,
	which is the current category shown. If $categorypathprefix is set, category navigation will be
	shown, with per-category question counts if $categoryqcount is true. The nav links will have the
	prefix $categorypathprefix and possible extra $categoryparams. If $feedpathprefix is set, the
	page has an RSS feed whose URL uses that prefix. If there are no links to other pages, $suggest
	is used to suggest what the user should do. The $pagelinkparams are passed through to
	qa_html_page_links(...) which creates links for page 2, 3, etc..
