History

Oops, seems to be a long time since I've last commited jvm.

The list of changes: - added more verbosity - fixed interface methods inheritance - fixed virtual methods inheritance - fixed class member inheritance - added System.initializeSystemClass() call - fixed some thread stuff - added exception handlers support
