Constants inconsistence

[jagarsoft]

In v1.x it had no $:

public const NEXT_STATE = 0;

In v2.x was wrongly renamed to string:

static int $NEXT_STATE = 0;

Moreover, it does not use Enum like in Stubs examples.

Fortunately, change can be done without breaking backward compatibility

<?php
// Your code here!
class Ex {
    public const NEXT_STATE = 0;
    static int $NEXT_STATE = 1;
}

$a = new Ex();
echo $a::NEXT_STATE;
echo $a::$NEXT_STATE;
?>

but change must deprecate variables (with $)
