[Nitro] Some cleanup

Sure, go ahaid.  (But use `darcs mv` and not just move it :P)

Uh, I use it, and I don't think it's confusing to newcomers.  In fact I
use it in my tutorials to create some 'cushion' for beginners to show
them some stuff and tell them the 'standard' nitro project layout.

Mainly I myself use it to recreate the basic directories.  I remove
basically all files though...
Doing a `gen app foo` is easier than looking up where to get a
`fcgi.rb` for use with apache...

So, my vote is for not removing it completely unless something similar
is provided.
