Push state option

[eerwitt]

First try at implementing an option to support push state by rewriting all request URLs to use /index.html instead of the URL requested.

Does this conflict with other options? I'm concerned about changing the requested URL.

This was originally requested as part of #80

Noticed that this doesn't work well if you're including JS files as well. Going to update to make it work as a fallback so if a file exists it is served.

Updated logic in 5dd25b5.

I agree with @indexzero, this is a better implementation than #205. +1 for the merge.

@indexzero Could you merge this?

Nice implementation that doesn't disable directory listing. It looks like somebody has published it to npm: https://www.npmjs.com/package/spa-http-server.

Used the spa-http-server npm package as suggested and then enabled the --push-state option. Works like a charm. Thanks!!

Has anyone here tried it along with setting proxy option for http-server (-P www.something.com)?
It works for me as long as I am not setting the proxy.

How to use spa-http-server in SPA mode:

1. Install it with npm i spa-http-server -g. It installs 2 global binaries hs and http-server.
2. Use it http-server --push-state.

This is what you should see:

@ekulabuhov, thanks for this! Where is the code for this spa-http-server fork?

Could this be merged over? It's an amazing feature and spa-http-server works like a charm for me!

We're adding a "self-proxying" approach to the README to address this issue, see #513

That should address this sort of usage without breaking the focus of this project on providing accurate HTTP responses. spa-http-server is available as a fork which focuses on SPA usage.
