[Nitro] Simpler configuration method?

George and I (and some others) discussed on that in #nitro for a
while.  I managed to bring George away from the $global idea,
his current take on it is (I hope I get that right):

class Nitro::Conf < Hash
end

class Nitro::Compiler
   Conf[:Compiler_mixin_get_parameters] = true
end

Which I found at least better than using 400 $globals just for the
Nitro internal configuration...

But, the namespace issue still stays.  It's possible (since this is
a single hash) to override stuff accidentally.  It also looks uglier
than:

class Nitro::Compiler
   setting :mixin_get_parameters, :default => true, :doc => "/meth?a=foo like /meth/foo"
end

Where each Klass gets its own namespace for settings.  Implementation
is slightly more complicated of course, also there are some issues with
'configuring not yet defined classes' (which is possible though, just
not as visually pleasing).

The current system also has the advantage of being able to view settings
nicely 'threaded' at run-time, even with documentation.
