updates and upgrades and adds support for esm, jsx, and typescript

[jeremy-coleman]

a few things here

1. added sucrase so esm, jsx, and typescript just work with practically no impact on bundling speed.
2. copied watchify-middleware internally so that watchify/chokidar deps match (and fixes install warnings);
3. added an option on the budo config to write output to disk, there is a working example in the 'start-demo.js' script
4. added a typescript version of the basic demo app
5. removed babel from dev dependencies
6. changed default ip to localhost, and new config object for useLocalNetworkIp (boolean)
7. updated tests, and a couple new ones for the localhost changes
8. inlined reload-css and updated the url and query-string deps to native-url and querystring. 21kb -> 11kb.
9. updated postinstall script to just use tinyify instead of uglify-js because it's way easier/better.
10. added getPort logic (copied from wmr)
11. added default extensions to the browserify config, [js,jsx,ts,tsx]
