Allow per config retrieve statements.

[joewalnes]

I'd like to do this:

config build
  retrieve CLASSPATH->lib
  include some/stuff
end

config runtime
  retrieve CLASSPATH->dist/lib
  include other/stuff
end

Is the goal to be able to copy the same files to different places? Or to control when the retrieve happens for different files?

[joewalnes]

The latter - I want to put dependencies for different configs in different directories.

Another example (from duplicate issue #55):

config production retrieve CLASSPATH->deployment/jars include foo/1 end

config test retrieve CLASSPATH->tmp/jars include testing-framework/1 end
