mod_autoindex was only checking for exact matches of "text/html"
	for ScanHTMLTitles, which meant that "text/html;charset=foo"
	documents wouldn't be scanned.  As a side effect of this patch,
	add ap_field_noparam(), which returns the unparameterised value
	for any HTTP field that can use '*( ";" parameter)'.
