Features
Support for the @mixin docblock annotation, which allows a class to proxy the methods and properties of another.
I also made a slight change in how magic getters & setters are dealt with – Psalm will emit an UndefinedMagicProperty if you define a docblock @property string $foo and then request the unlisted property $bar. If you wanted this behaviour previously you had to also annotate your class with @psalm-seal-properties. This is now assumed if you provide a @mixin or @property annotation for the given class. In the event the property is missing, Psalm now emits an UndefinedMagicProperty issue that you can suppress in a more granular fashion.
