[Tutorial] Using funcdefs

[DRedshot]

Thanks a lot for taking the time to write this tutorial. It's really useful for people like me, who has barely touched any programming languages, but has learned almost everything there is to learn about angelscript, and wants to know more! I think i understand most of it, but it will take a few more readthroughs and a couple of google searches to fully understand arrays. keep doing things like this!
