[Feature Request] Price reflects Edition and/or Foil

In addition to using deckbox.org as a way to keep an inventory of my cards, I'd also like to use it as a real-time tool to keep track of my cards' true value for trading at events.  I've noticed that the quoted price does not change at all when you toggle Foil on or if you change the set to an older edition.  For example, strip mine shows an average price of $3.65 but that's for the 4th edition.  The antiquities version has an average price over twice that at $8.00.

One simple way to account for the foil prices (at least in the interim) is to have a user-definable "foil factor" which multiplies the average price by 'X'.  A default value of 2 should suffice.

Oh, and I'd also like the option to separate foil from non-foil entries so I can see at a glace how many of each of the same cardname I have.

Thank you so much for this great site, I'm looking forward to see what great things are to come.
