obsfate: rename obsfate into obsolete in changeset_printer
Yuja's comment on the original obsfate about how we would translate obsfate
and the recent discussions about exposing users to new concepts and names lead
have led me to think that 'obsfate' should be treated as internal jargon. End-
users should not be aware of obsfate, so we replace 'obsfate' by 'obsolete' in
changeset_printer.
It will be easier to understand for end-users, easier to translate and closer
to the original Evolve obsfate output.
I'm aware it's extremely late in the cycle but I think it's an UX improvement
for the end-users.
