Hello Christophe,

I'm a boost msm first time user and I'm attempting to pass an event to my
msm that cannot be copied.
This event contains a /unique_ptr/ and my goal is to eventually steal it and
store it under my msm.

However, even with no deferred events, events are /copied/ to an internal
queue, in /boost::msm::back::state_machine::do_pre_msg_queue_helper/.

I just wanted to know if there was any chance /process_event/ could be
overloaded and accept rvalue-ref or if by design, it's absolutely mandatory
to copy those events.

Many thanks for your great library
