Added ability to use wildcard in allowed state changes

[jezzdk]

Summary

This will add functionality that allows the user to use wildcards when defining state changes. This can prove useful if you have a lot of states and you dont want to type them all in when everything is allowed.
For example:

// If it should be possible to change from any state to a given state:
return [
    '*' => [
        'approved'
    ],
];

// If it should be possible to change to any state from the 'pending' state:
return [
    'pending' => '*',
];

// If it should be possible to change to and from any state whatsoever:
return [
    '*' => '*',
];
