you gotta do encodeAsURL for anything in the URL

In testing spotmouth, came across some spots that had ampersands in the names.  I put the names in the URL (heard it's good for seo), but when I did a request for the spot with the ampersand in it, I got a 404.

I needed to call the "encodeAsUrl()" on the values that could contain these types of characters.  here's an example of what I am doing:

                 <g:link target="_self" action="spotdetail" id="${item.getFieldValue('spotid_l')}" params="[name:item.getFieldValue('spot_label_s').encodeAsURL()]">
                                      <g:if test="${item.getFieldValue('image_thumbnail_57x57_url_s')}">
                        
                            <img   src="${item.getFieldValue('image_thumbnail_57x57_url_s')}" />

                        </g:if>

                     </g:link>
