v9.1.1

• Fixed numerous issues with doubling that were caused by the port from 3.x. Most of these involved using the INCLUDE_NATIVE doubling strategy.
• Added errors and better failure messages when trying to stub or spy on an invalid method. For example, if your script does not implement _ready and you try to spy on it, your test will now fail since _ready is virtual and you didn't overload it.
• Doubled methods that have a vararg argument are now auto detected and extra parameters (up to 10) are added to the method signature to handle most use cases (i.e. rpc_id, emit_signal). If you call a doubled method that has a vararg argument and you have not stubbed param_count on the object's script then a warning is generated.
• Fixed an issue where command line would not launch in 4.2rc1.
• Issue #510 Added all types to strutils to address #510.
• Issue #525 Signals are now disconnected when waiting on signals that do not fire in the expected amount of time.
