kmd diff tool

[pinkwah]

I want to write kmd diff 2020.02.01 2020.03.01 in a releases directory or kmd diff stable-py2 testing-py2 --root=/prog/res/komodo for deployed and have a nice diff of changes, with colours and emojis. The output could be divided into four sections. A is the first argument, B is the second:

• Updates: Exist in both; version in A is lower than in B
• Downgrades: Exist in both; version in A is higher than in B
• Additions: Exist in A; don't exist in B
• Deletions: Don't exist in A; exist in B

Additionally, adding a --markdown (-m ?) flag would print markdown output that can be copy-pasted into Slack or Github.
