My Cards Initial Cleanup. 

I still want to add useful info to the Block/Set panel headings and footers. This can wait for another release since it will like require more convenience methods (i.e. rarity counts and totals by planeswalker & set).

Something I left in intentionally (if only temporary):
When you reduce an owned card to 0 and you are only viewing owned cards, right now it turns grey (until you refresh the page). I contemplated deleting the card in that case, but settled on leaving it for now for the sake of convenience. Say you accidentally reduce it to 0, you can quickly add 1 back. Thoughts? 

Fixed previous issues:
-Binder view: when you set a card to 0 owned turn grey
-My Cards: When viewing all cards in set, non-owned should be grey
-My Cards: Return number correctly when adding/removing cards

Minor page and style edits.
