Removed default ingest menu, ingest configuration can now take a object.

Was not in use and excepting any parameters for the ingest process via GET
was not very safe.

Also the ingest configuration can now take an NewFedoraObject rather than
building one from the configuration options. The old way is still supported
for now though.
