Introducing demoSHACK

[Habluka]

If you haven't already I think it'd be a good idea to only allow .dmo files. Some time ago someone else did this and I remember someone was trolling and posted weird pics. Good job :)

Unless you write something that will actually verify that it is a demo file, that would be kind of pointless since you can put a .dmo extension on anything and trick people into downloading it. Unless it becomes a problem, I really don't see a need for that.
