added spanish translation. fixes #883
Because a shared options object is passed around when creating each instance of a select2 widget, the query function that was built would use the last ajax url that was set on the options object for all select2 widgets. By using a variable scoped to the closure, the ajax url can be maintained per select2 instance.

Remove -o-box-shadow since it is not needed.

Opera implements box-shadow without a vendor prefix, so -o-box-shadow
is invalid.
