%const in C++ specification of predefined MPI objects

MPI-2, page 345, line 37: Remove the const from const MPI::Op.
MPI-2, page 346, line 20: Remove the const from const MPI::Group.
MPI-2, page 346, add after line 34:
Advice to implementors: If an implementation does not change the value of predefined handles while execution of MPI_Init, the implementation is free to define the predefined operation handles as const MPI::Op and the predefined group handle MPI::GROUP_EMPTY as const MPI::Group. Other predefined handles must not be "const" because they are allowed as INOUT argument in the MPI_COMM_SET_NAME/ATTR and MPI_TYPE_SET_NAME/ATTR routines. End of advice to implementors
