V3 -> V4 Changelog about mtgjson-website

[ancestral]

I think this looks great!

This should be linked to from the webpage as well.

Here are the changes from the initial v4 try as reference, maybe there is a leftover and somebody can file an issue for important missing "features" for later?
https://github.com/mtgjson/mtgjson4_temporary#new-features-and-changes
I think stuff like changes to the filenames/merge of -x files should be listed here too.

New features and Changes

• Persistent immutable ID, generated for each card, stored on "_id" field.
• JSON database stored on a different project
• Sorting
  • All objects with sorted keys
  • Card arrays are sorted by number, then by multiverseid
• Command line interface for adding, removing and querying substitution rules
• Files provided on the website will be pretty-printed (instead of one-liners)
• Incorporate tokens
  • Tokens will also have unique "_id" fields.
  • Tokens will have their own array, separated from the cards array.
  • Tokens will have a "card generator" array, provided they are from the same set.
  • Initially, tokens will be parsed from a sub-repo of the Cockatrice project:
  • Cockatrice/Magic-Token:tokens.xml@master
• Fields that will be removed:
  • id
  • imageName
• Set Specific
  • EMN
    • Try to look for meld cards automatically with the "Melds with (card-name-here)." on text.
• New provided files
  • AllCards_Standard.json
  • AllTokens.json
• Filename alteration: the "-x" suffix will be changed to "-full".
• Every file will have a ".sig" file as well.
