Replace table on search page

[graft]

The table widget on the Search page is famously bad. Everyone hates the resizing columns and it is difficult to navigate.

A better alternative might be https://facebook.github.io/fixed-data-table/, a React table that seems like it would do better - fixed columns especially seems like a nice feature to enable (click column headers to freeze and unfreeze them).

What renders in the table cells should continue to use AttributeViewer to display content.
