multiple selects don't work in the elements plugin

[bluesodium]

In the elements plugin:

1. the multiple select only posts one value
2. when clicking back the selected array is not updated and it is added to every time.

this can be tested by using the default emy form post function (only posts one value)
if you change the form method and add target="_self, you can see the multiple values.
if you click back and change the values these are not representative of the selected values

after a bit more investigation looks like there are two issues.

1. the emy form parser doesn't seem to cope well with multiple selects, in fact it only selects the first value. To replicate go here -> link. (SELECT MENU/SELECT MULTIPLE) Select all the values and submit the form. Only one value is displayed.

2. the multiple select just doesn't work - select all six items in the multi select list here - link (SELECT MENU/SELECT MULTIPLE) Once selected, unselect them all, go back (the list displays nothing) and submit the form. you will see values have been submitted.

fixed Issue 1.

added in a check for a form multiple:

if (input.getAttribute("multiple")) {
    args[input.name] = getSelectValues(input);
}
else if (value === undefined) { // If parm is 'empty' just set it
    args[input.name] = input.value;
} else if (value instanceof Array) { // If parm is array, add to it
    value.push(input.value);
} else { // If parm is scalar, change to array and add to it
    args[input.name] = [value, input.value];
}

and added function to parse the multiple values

    function getSelectValues(select) {
      var result = [];
      var options = select && select.options;
      var opt;

      for (var i=0, iLen=options.length; i<iLen; i++) {
        opt = options[i];

        if (opt.selected) {
          result.push(opt.value || opt.text);
        }
      }
      return result;
    }

retested issue 2:

1. works on ios/android
2. doesn't work on any desktop browser

works for targetted device (so good), but makes it hard to test on desktop....

Any ideas why values once selected remain selected (even when unselected) on desktop gladly received.....
