add quick-dapp plugin

[drafish]

Try it here -- https://remix-quick-dapp.vercel.app/

Here is the explanation for the references in code.

https://remix-dapp.pages.dev is the domain of the dapp template.

https://remix-dapp.pages.dev/manifest.json is the json file contains all the static files paths of dapp-template. It's generated through the build process automatically.

Before the dapp deployment, quick-dapp plugin will get all the static files paths of dapp-template, and download them from the dapp-template domain.

https://vercel-proxy-bice-six.vercel.app is the proxy to resolve the cross-domain issue. Because the backend service of surge does not support cross-domain.

Here is the codebase of the dapp-template https://github.com/drafish/remix-dapp Here is the codebase of the proxy https://github.com/drafish/vercel-proxy

They are not in the remix codebase.
