Movable ScopedRemover about eventpp

That's good idea. I will check.

My idea was to be able to put it as a member variable that would manage the lifetime of the event subscriptions.
With it being movable it would be easier to assign this member outside of the constructor.
The drawback would be that you could move and keep alive callbacks referencing a dead /moved object. And that could lead to nasty surprises.

Added move constructor and move assignment operator on master branch.

ScopedRemover should be used in the way that, the underlying listener objects should not have longer lifetime than ScopedRemover. If we follow that rule, no matter how it's moved, it's safe and should not any crash.
