Experimental SSR Support

⚠️ If you are a user of Astro and see this PR and think that you can start deploying your app to a server and get SSR, slow down a second! This is only the initial flag and very basic support. Styles are not loading correctly at this point, for example. Like we did with the --experimental-static-build flag, this feature will be refined over the next few weeks/months and we'll let you know when its ready for community testing.

Changes

This adds a new --experimental-ssr flag to astro build which will result in dist/server/ and dist/client/ directories.

SSR can be used through this API:

import { createServer } from 'http';
import { loadApp } from 'astro/app/node';

const app = await loadApp(new URL('./dist/server/', import.meta.url));

createServer((req, res) => {
  const route = app.match(req);
  if(route) {
    let html = await app.render(req, route);
  }

}).listen(8080);

This API will be refined over time.
This only works in Node.js at the moment.
Many features will likely not work correctly, but rendering HTML at least should.
