add instructions to update/restart dummy app and jetty
Use the new DPLA marmotta-jetty

This unifies us on a single servelet container for Solr and Marmotta.
It also pins us to a snapshot of Marmotta 3.3.0, which current LDP
work depends on. We're expecting an official 3.3.0 release imminently.

When building for the first time with this update, you may need to
remove any lingering Marmotta files by doing `rm -rf /tmp/marmotta`.y

Update LDP-NR OriginalRecords for Marmotta 3.3.0

The latest version of Marmotta changed how `Content-Type` headers are
handled in POST/PUT requests for creating LDP-RS vs. LDP-NR.
`text/plain` is now assumed to be an RDFSource.

We should find a good way to create/maintain LDP-NR's with content
types like `text/plain` and `application/xml`, for which Marmotta will
try to create an LDP-RS. This may be an interaction model thing.

In the meanwhile, OriginalRecords are created with a Content-Type of
`application/octet-stream`.
