The datagrids once had a facility for the entire row to act as a link to

the given object. Over time as we made changes, this functionality had

been about halfway erased, making it so only cells with .has-link

worked as links despite the entire row having a pointer icon. This

change fixes up things so that the URL is set correctly on the tr

element's data, and recreates a javascript handler for clicks that are

otherwise unhandled.

Clicked on various cells within different dashboards and checked to

ensure that the correct page was loaded. For cells that contained their

own link (for example, users), saw that the row-level link was ignored

in favor of the cell-level link. Verified that clicks on

interaction-type cells (stars, checkboxes) did not activate the link.
