Change "box" terminology to "entry" for the review request page.
Review Request #9110 — Created July 31, 2017 and submitted
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.
