Add UtilityClass::Int()
This is simply a wrapper function around SDL_atoi(), because SDL_atoi() could call libc atoi(), and whether or not invalid input passed into the libc atoi() is undefined behavior depends on the given libc. So it's safer to just add a wrapper function that checks that the string given isn't bogus.
