#22 Fix for checkboxes not working when PersistentCheckBoxes is set to false

[Prommah]

In 2.8.0 the part of the method FillInValues that handles checkboxes in ObjectListView.cs was changed, which broke checkboxes when PersistentCheckBoxes is set to false. Here is a fix:

             // Set the check state of the row, if we are showing check boxes
             if (this.CheckBoxes) {
                 CheckState? state = this.GetCheckState(lvi.RowObject);
-                lvi.CheckState = state ?? CheckState.Unchecked;
+                if (state.HasValue)
+                    lvi.CheckState = state.Value;
             }

             // Give the RowFormatter a chance to mess with the item

Since GetCheckState will always return null when PersistentCheckBoxes is false, in 2.8.0 & 2.8.1 lvi.CheckState would be forced to CheckState.Unchecked, making checkboxes uncheckable. Restoring the previous code seems to resolve the issue.
