Writen by Windexglow 11-13-10. Use it, edit it, steal it I don't care.
Converted to C# 27-02-13 - no credit wanted.
Simple flycam I made, since I couldn't find any others made public.
Made simple to use (drag and drop, done) for regular keyboard layout
wasd : basic movement
shift : Makes camera accelerate
space : Moves camera on X and Z axis only. So camera doesn't gain any height*/
