Start experimental version for WebSocket

[bsjung]

I've tested WebSocket v0.4.0.

It works but, it is not compatible with flutter websocket format.
Most websocket client send without name, it is also flutter packages.

Thus, I've made expremental start v0.5.0 on github.

And I've made start web frame examples.

Benjamin, can you please submit a Pull Request with your changes?

[bsjung]

Ok. I'll setup git pull request. But, it takes a time.

I think simple jwt plugin will be helpful to my project and others using start web framework.
Thus, I've making another JWT token plugin for Start web framework.
