New Script FlyCamera add to any camera obj: instant unity editor style wasd rightclick debug cam

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*/
