QtRpl/RplSearchReplaceDlg.hpp
QtRpl/RplSearchReplaceDlg.cpp
QtRpl/RplSearchReplaceWidgets.ui
--------------------------------

Qt4 Port: Q3ListView --> Qt4 QTreeWidget

  OLD: Q3ListView*  _ui._searchResultsListView
  NEW: QTreeWidget* _ui._searchResultsTreeWidget

  OLD: class RplSearchReplaceDlg::RplQViewItem : public Q3ListViewItem
  NEW: class RplSearchReplaceDlg::ResultItem   : public QTreeWidgetItem

New Qt slots (signal handlers):
  void searchResultsTreeWidget_itemDoubleClicked (QTreeWidgetItem*, int col);
  void searchResultsTreeWidget_itemSelectionChanged();

Removed from the item class:
  virtual QString key (int column, bool ascending) const;
  virtual void paintCell (QPainter*, const QColorGroup&, int col ...) 

Added to the item class:
  virtual bool operator< (const QTreeWidgetItem& rhsItem) const;
  int compare (const QTreeWidgetItem& rhsItem, int col) const; // private
   ... isolates numeric text before the colon for numeric sorting.

Configuration symbol:
  static const bool USE_ALTERNATING_ROW_COLORS (true);

Minor: One Q3GroupBox changed to a Qt4 QGroupBox. (Trivial).
