3 new example Snaps, all open-source

[Montoya]

I want to share 3 new example Snaps with everyone.

First, an Address Book Snap Tutorial that teaches how to manage state inside of a Snap.

Next, a Password Manager Snap that stores data securely with encryption, using the entropy derived from MetaMask for Garlicoin.

Finally, a fully working Bitcoin Snap developed by Keystone!

Working on something cool? Share it here!
