Subject: The ListWidget constructor already did most of what reflowLayout()
 does, except calling Widget::reflowLayout(). I've simplified that by calling
 reflowLayout() directly instead. This may be a bit of a hack, but it was the
 best way I could think of to ensure that _entriesPerPage was properly
 initialised. It wasn't before, because _h had not been initialised, causing
 Valgrind to complain.
