Remove unused import
Revert previous change to identify links with short hash value of name + label.  This caused some unwanted tests failures the use the Link header to identify which link was used and what the next resource should be.  Ideally we could move this link id logic into interaction-core, but not right now.
Add a couple of rel values to Simple.rim to better demonstrate the use of link relations.
Add a map of links by rel values.
Moved the HAL Browser name / index column to the end so we can at least see the docs and GET link buttons.
