Remove demeaning descriptors 

Removed "Ninjas, Rockstars, and Samurais" in place of Developer as I'm fairly certain very few people on the list are actually trained Ninjas or Samurais and while some might be in bands they are most certainly not rock stars (I mean, if they are, why are they still writing code?)
Changed Developers to Heroes
