Updated for Dat 2

[RangerMauve]

• Use Dat2 from the SDK
• Use promises instead of PDA and the such
• adds dat-store clone <folder> <url>
• Removes local discovery-swarm-web (for now)
• Remove support for .dat folder from CLI
• Use names feature of Hyperdrive for creating writable archives
• Use .dat file in folders to identify. Contains either a dat:// URL, or a uniquely generated name

TODOS:

• [x] Test loading archives from the network
• [x] Test invoking dat-store clone
• [ ] dat-store create?
• [ ] Exporting / Importing private keys for cloning?
• [ ] Add local hyperswarm-web proxy?
• [ ] Local gateway of some sort?
• [ ] Make localhost detection more robust

Out in dat-store@next if anyone wants to test

There's still some nice to haves that could be added, but I think this is good to go with the latest version of the SDK.
