Function: checkText()
Input: three array: arr_field contains text_field_name in the form

                    field_attr contains text_field_attribute. They're: maxlength or maxvalue (for
                    number field).
Output: one array: arr_result contains boolean values or a String value "null" if this field is null.
"long" if too long.
Purpose: check all text fields in the form.
