As someone who has some very old dominion cards (from the very first printing, in some cases), many of my physical cards have had errata issued for them, so the "official" text doesn't match what's printed on the card any more.

I'm working on updating this code to include the most up-to-date official text, but it might be nice to show a little "E" on the tab somewhere for cards that have errata. Naturally, it would be an option, since that's what we do around here ;)

Some ideas about how this would work:

• Render a small "E" above and to the left of the set icon if a card has errata.
• Get lists of all the cards that had errata issued in each year (there have been a handful), and add that data to the card db. Add an "--errata-since" argument that takes a year and sets the errata flag to true for all cards which had errata more recent than that year.

Anybody else have any ideas/feedback?
