Return partial template when using AMD

[baluubas]

I'd love to see the possibility of returning a partial template when wrapping with AMD.

For example something like this:

partials.push('var partialTemplate = ' + compiled + ';');
   if (options.partialsUseNamespace === true) {
      partials.push('Handlebars.registerPartial('+JSON.stringify(filename)+', '+nsInfo.namespace+'['+JSON.stringify(filename)+'] = partialTemplate);');
} else {
   partials.push('Handlebars.registerPartial('+JSON.stringify(filename)+', partialTemplate);');
}
if(options.amd && options.namespace === false) {
   partials.push('return partialTemplate;');
}
