#88 support rvalue reference for result type (or Boost.Move)

[Lorenzo Caminiti]

= return =

" Rationale. The result type needs to be copyable in order for the
function itself to return a value so this library can always evaluate return
value declarations."

This is only true if rvalue references are not supported. Otherwise, for
MovableOnly types the variable used to store the return value could be a
rvalue reference and move semantics should be applied.
Even if you don't support C++11, the user can use Boost.Move.

I think so. I don't mention rvalues at all (emulated nor C++11) in the
docs... I can add a few notes about rvalues when supporting C++11.
