Added selectColorOption

[vinmenn]

Hi I have added a small mod to use selectColor inside option block, in this way is possible to use both selectColor and other options:

    $('select[name="colorpicker"]')
     .simplecolorpicker({ theme: 'glyphicons', selectColor: '#e1e1e1' })
     .on('change', function() {
     $(document.body).css('background-color', $('select[name="colorpicker"]').val());
     });
