Replacing q with searchconfig in select2 autocomplete boxes
Removing unused code from itemdetails
Fixing row colors on item table.

The table rows in the Item table were not previously colored correctly.
This commit brings them in line with the issues table.  Issueless or
Scoreless items have no color (white).  Items with only justified issues
are green (bootstrap "success").  Items with 3 or fewer unjustified
issue points are colored yellow (bootstrap "warning").  All other items
are colored red (bootstrap "danger").
