Generate a $proxy class for all abstract classes and use them when the return type is abstract,
similar to interface proxies.
This change also adds
abstract: true
to all interface members, so the proxy generator can treat interfaces and classes polymorphically.Added a compliance test "returnAbstract" which verifies this behavior.
