Great but minor errors!

Hi,

Thanks very much for this plugin. A couple of errors:
– Spanish translation has one error. First the message addresses the user as “usted” and afterwards as “tú”.
-When saving the settings through the admin panel, the custom css textbox introduces escaping characters (‘\’) to the css rule that applies the Close icon. At least that has been my problem on Firefox 29. As a result, the Close icon does not show up, and after saving settings more times the css rule ends up like this:
background:transparent url(\\\”../img/close.png\\\”) no-repeat center center;
(Wrong escape characters before ‘ or “)
