Make the relationships case-insensitive (esp. for the Traceability matrix)
Some customers have issues with columns which have been built for "Req_ID", and since 2.0.0, relationships are lowercased to "req_id", so the columns appear empty. We need to make the traceability matrix, case-insensitive.
Also, we'll provide a way to edit the JSON of the traceability matrix, in case one needs to debug it... As much as we'd like to hide complexity, our current failure mode is to drop a matrix entirely, and this is not fun.
