14275	Proper error reporting in scriptloader for all browsers.	kkrzton	kkrzton	"While working on #13943 there was a need to check if config scripts were loaded successfully. It is partially supported by scriptloader but not for all browsers (IE < 11, Safari, Opera - probably before migrating to Webkit). It is not really supported by those browsers in a proper way but still it may be needed in the future so probably should be done.

{{{
if ( CKEDITOR.env.ie && CKEDITOR.env.version < 11 ) {
    // FIXME: For IE, we are not able to return false on error (like 404).
    script.$.onreadystatechange = function() {
        ...
} else {
    ...

    // FIXME: Opera and Safari will not fire onerror.
    script.$.onerror = function() {
        ...
