This pull request proposes an enhancement to the existing code that deals with testing the presence and values of properties on an object.

Currently, the toHaveProperty() and toHaveProperties() methods can be used to test for the existence of properties on an object.

expect($object)->toHaveProperty('name');
//or
expect($object)->toHaveProperties(['name', 'age']);

However, to check the value of a property, only toHaveProperty() is available.

expect($object)->toHaveProperty('name', 'Daniel San');

This PR adds the functionality of testing multiple properties and their values using the toHaveProperties() method using an associative array.

expect($object)->toHaveProperties([
     'name' => 'Daniel San',
     'age' => 50,
]);

Is it plausible that this feature could be expanded at some stage to architecture testing? The use-case would be asserting that all classes in our "Actions" namespace have a single public execute() method.
