title: Stop jqGrid row being 'selected' when clicked, while still preserving editing
body: <p>I have a jqGrid with three columns. One of the columns is set up for cell editing, like so:</p>
  
  <pre><code>$('#myGrid').jqGrid({
      ...
      editUrl: 'clientArray',
      cellEdit: true,
      cellsubmit: 'clientArray',
      colModel: [
          {name: 'Col1'},
          {name: 'Col2'},
          {
               name: 'Col3',
               editable: true,
               editrules: {required: true, number: true}
           }
      ]
  });
  </code></pre>
  
  <p>When the user clicks on a cell in the third column then the editor automatically appears. However, when the user clicks on a row, that row also becomes highlighted ('selected'). <strong>Is it possible to disable this highlighting whilst still allowing the cell editor to be displayed if the user clicks on a cell in the editable column?</strong></p>
  
  <p>I've tried</p>
  
  <pre><code>$('#myGrid').jqGrid({
      ...
      beforeSelectRow: function() { return false; }
  })
  </code></pre>
  
  <p>...but this disables editing as well as the selecting of a row.</p>
