When running multiple instances (eg. Debug->Run Multiple Instances->Run 3 Instances), there is no automatic way to tell one instance to behave differently to the others (eg. you might want one instance to host a game and the others to join it).
When running more than one instance, this PR adds an argument accessible through OS.get_cmdline_args() for the index of the instance. Each instance will always be assigned a different number from 0 to n-1 for n instances.
