Add equals() methods for wrapper classes

[thekid]

Example

The following code becomes clearer:

  $user= ...
  foreach ($comments as $comment) {
-   if (0 === $comment['user']['id']->compareTo($user->id()) {
+   if ($comment['user']['id']->equals($user->id()) { 
      // Comment was made by user
    }
  }

Wrapper classes

These classes now have an equals() method alongside compareTo():

• ObjectId
• Int64
• Decimal128
• Code

The MinKey, MaxKey and Timestamp classes do not have this method.
