Rename 'Components' to 'Additional Work'.

I think I'm wrong about scenario 1: because of the way Separate Works are defined.
'Enhancement or extension' of the Covered Work is not 'Separate Work'. These
'Component' (i) seems useless, because 'enhancement or extension' is better off
as 'Derived Work'.
Will come back on it.
