[Nitro] Smarter nitro executable

[Arne Brasseur]

Another idea I've had, if the nitro executable would be able to figure 
out if it's installed as a gem or not, it could in the second  case take 
care itself of setting the loadpath for nitro. That way when running 
from the repo you wouldn't have to juggle too many environment variables 
and the likes, it would "just work".

Opinions?
