Using references matches the C++ coding style better and should improve performance a bit in theory. It avoids 2 copies of T in case of the functions registered with RegisterFunction (mainy used in the GUI). It should also avoid one or two copies in case of DEFINE_INTERFACE_METHOD_X, which is used in the simulation, but I haven't bothered to count it there exactly. It is now predefined which types have to be passed by const reference and which are passed by value. Note that references can't be used as out-parameters (to return multiple values to JS). This hasn't worked before either and probably never will. This was SVN commit r17696.
