Length of database fields for lot and serial no don't match with entry length

In VPAttributeDialog.java the displaylength and the fieldlength for both serial number and lot is set to 20, the database fields and the web client allow 40 characters.

{{ // Lot
private VString fieldLotString = new VString ("Lot", false, false, true, 20, 20, null, null);
}}

{{ // Ser No
private VString fieldSerNo = new VString ("SerNo", false, false, true, 20, 20, null, null);
}}
