[validate] option witout no value crashes in i.e.

[hasantayyar]

with Validation plugin this cause a crash in i.e. (I've tested in i.e. 8)

<option>text</option>

I debugged the script and see that line cuse the srash

(line 890)

case 'select':

var options = $("option:selected", element);

...

so this beacuse of "no value attribute".

If there is no value attribute the form gets the inner text, and the validation should get the inner text, too.
