Title: Make LiftResponse header defs vals instead

Because most LiftResponses are serialized to InMemoryResponses
after the end of the S scope, the LiftResponses that have def headers
instead of vals and rely on S.getHeaders are completely broken (they omit
all headers).

To fix this, we need to make all of those defs vals instead so that they
properly look up the S headers while S is initialized.
