Validator: selector escaping

[heruan]

Some characters, though valid in <input>'s name attribute, need to be escaped to be used in jQuery selectors such as $('[name="' + selector + '"]'). Validator should take care of these selectors to-be-escaped, i.e.

$('[name="' + selector.replace(/([;&,\.\+\*\~':"\!\^#$%@\[\]\(\)=>\|\\])/g, '\\$1') + '"]');
