color was never being set properly

neither the default color (#bababa) nor a user-specified would ever be set right because the **color** attribute was being accessed at the base options object instead of on the nested **placeholderCSS** attribute. as a result, the browser would always use the current styling for the plugin's generated label element.

i manually change the minified file as well, but you may wan to re-gen that, though i doubt it would change the outputted code.
