Fixing sample two column layout of Address

I've added a fix based upon my comment on the page on alpaca.js to resolve the issue where the two column layout isn't shown for the address field.

I tried to update the code so that it would work with the given sample but I'm not terribly familiar with the alpacajs codebase and thus don't have a concrete understanding of how to properly make the changes.  I'm hoping to come back to review it at a later date.

I was experimenting with changing the field template lookup to check for a template on the layout property around like 3568 of the current version of alpaca.js

                            if (view.fields[path].layout && view.fields[path].layout.template)
                            {
                                var template = view.fields[path].layout.template;

                                functionArray.push(function(normalizedViews, view, compiledTemplateId, template) {
                                    return function(totalCalls) {
                                        compileViewTemplate(normalizedViews, view, compiledTemplateId, template, totalCalls);
                                    };
                                }(normalizedViews, view, "field-" + path + "-fieldSetItemsContainer", template));
                            }

I also added code around 3695 to set the template
                // field layout template
                if (templateId == "fieldSetItemsContainer" && view && view.fields && view.fields[path] && view.fields[path].layout && view.fields[path].layout.template) 
                {
                    _template = view.fields[path].layout.template;
                    _templateType = "field";
                }

The problem was around 2486 where the wrap functionality is.  The code doesn't do a lookup of the template based upon the label when the wrap parameter is set to true.

I wasn't entirely sure how to account for that and include a template lookup.  I also am not certain that the fieldSetItemsContainer is the correct override to be used in this case.

None the less, I thought I'd share my efforts in hope that someone with a bit more familiarity can take a look
