Title: Add an error for platforms that can't use Game.Exit()

Many of the supported platforms discourage programs from terminating themselves, and some [outright prohibit it](http://msdn.microsoft.com/en-us/library/windows/apps/hh464925.aspx#close) as a matter of policy. This PR will throw a compiler error for those platforms where it would otherwise be rejected from the store later on.
