<!--
ListViewItem control template and style.  This is used for the main code ListView.  The
most significant consideration is getting long comments and notes into the 5th column and
having them span multiple columns.  Most of this came from the default style (WPF 4.5).

This interacts with DisplayList.FormattedParts.
