Suppress a warning in msvc 64bit builds...
Suppress a warning in msvc 64bit builds Using std:sort causes warning C4267 in 64bit msvc builds, because size_t and int are of different size. There should never be a case where list indexes grow so large that this causes problems, so just suppress the warning.
