Multiple checkbox not restore data

[cdevassine]

Hello, First of all, thanks for this code, it is really excellent!

I noticed a bug since v1.1.3 about multiple checkboxes (bug is not present in v1.1.2).
Since v1.1.3, the getElementIdentifier() function retrieves the ID and name of a field.
In fact, it fails to restore data from multiple checkboxes.

I fixed on my local code with this :
function getElementIdentifier(el) {
//fix get Multiple Checkbox []
var name = el.attr( "name" );
if ( name.indexOf( "[" ) !== -1 )return '[name=' + name + ']';
return '[id=' + el.attr( "id" ) + '][name=' + name + ']';
}

but it's not necessarily the best.
Any idea ? ;)
thank you very much !
