New Features
Change the font and size of items in the popup (Settings → Font / Item size)
Unit prices below 10¢ show more digits (e.g. $0.0053 instead of $0.01)
New setting: Calculate precise unit price. Amazon rounds unit prices to the cent, so this recalculates them from the quantity in the title

Bug Fixes & Improvements
Coupon, subscription and quantity discounts now work with Compare Units By Category (they were compared in the wrong unit)
The item price now shows the same discount as the unit price
Fixed "Coupon price $X" coupons being subtracted as a discount (e.g. $32.99 showing as $3.30)

Fixed bug where last few items were not getting grabbed from page.

Fixed error where normalized unit price wasn't shown on weight unit or volume unit change in UI (but was shown on refresh).

Removing errant "Amazon" reference.
