Add logic to ensure that shared pointers are checked to be of the right width. The primary upshot is that if you declare AM_SHARE("paletteram") in an 8-bit memory map, then only m_generic_paletteram_8 will be populated, and m_generic_paletteram_16 will be NULL. But it applies to all required_/optional_shared_ptrs declared, so make sure they are of the right type. The required_/optional_shared_ptr mechanism should be used to replace AM_BASE_MEMBER and AM_SIZE_MEMBER, which are technically dangerous and illegal in C++ but work today through some trickery.
