fixed two errors

1. MM-dd-yyyy to yyyy-MM-dd
2. even for the non important alert views, if we click the 'other
button' a function called 'alertView: ClickedButtonAtIndex:' is called,
and the if statement is called. however this shouldn't be the case for
alert views other then date picking alert views. so I just disabled the
'otherbuttons' for the alert views that don't need to call the if
statement.
