Long strings in the review request details fields (on the right-hand side of

the fields) would increase the width of the entire table, eventually

overlapping the main fields in a very ugly way. This change adds a max-width to

the field spans, and specifies a word-wrap to force browsers to insert line

breaks in the middle of words in the case that it can't break at a natural

place.

Set a branch that was just one long unbroken string of characters and saw it

  wrap at the width of the details pane.
Checked that a bunch of comma-separated bug numbers still wrapped at an ideal

  place in the text.
