Make review comments standout more from the surrounding code

Review comments are now using the same size font, so the text is a
bit larger and easier to read.  They also use up a bit more screen
space vertically, so its easier to notice the comment block.

Comment sections have a thick orange border on the left and right side,
making them stand out visually from the other parts of the file.
We also color them with a light-peachish background color, which is
visually distinct from the light green or red used on other lines.
