This updates the JavaScript for the review request page to use "entry"
instead of "box" for the terminology, helping to make the code a bit
more readable and clear. It also fixes up some of the event and anchor
handling to be more efficient.

Tested that collapsing/expanding all and individual entries worked.

Tested entry expansion when anchors are referenced.

Unit tests pass.
