Autoconnect and password form.

Allows auto connect, host and port to be passed in URL,

spice.html?v=x&autoconnect=true&host=x.y.net&port=/wsproxy/5900/

Password form used if host has a password set.

And for my use case I have added/amended the following lines not included in the PR

Spice Javascript client

I know there is spice_auto but I was looking to be able to have a single version that could be used for either requirements.

Thank you for taking the time to review and let me know if you want me to raise in another location.

I have seen the TODO, but is there a formal published development road map?
