Deploying demo to https://dashhive.github.io/DashJoin.js/ momentarily. When we're a little further along I'll also deploy the mainnet version.

Demo is up at https://dashhive.github.io/DashJoin.js/

Since I've already verified the other domain with the DigitalCashDev org I'll wait until the next iteration to deploy it to https://coinjoin.digitalcash.dev and list on https://digitalcash.dev.
