Subject: [PATCH] Move list generation out of TablePager::getLimitSelect()

Added TablePager::getLimitSelectList() to get the list of values to
show for the drop-down so that it can be used to generate a custom
<select> or to be used on a form generated with HTMLForm.

Also changed HTML generation to use XmlSelect class.
