Configurable URI path prefix for http and stream

[easytarget]

Add ability to extend the path for the HTTP handlers; allowing easier embedding and providing a basic secrecy hurdle against casual viewers.

ie: define HTTP_PREFIX (eg mysecret/) and embed in all the URI's like this http://<IP>/$HTTP_PREIX<target>

Needs SSL support ( #54 ) to become a real privacy / eavesdropper protection, totally vulnerable to network sniffing without this.
May be very useful if you want to embed within another site.

Allow separate prefix for HTTP and STREAM handlers. Dont forget to pass this as part of the stream URL to the browser.

Just lost a couple of hours of my life to realising that this is a rather bad idea.
Closing; I'll submit a proper 'authenticate users' RFE later if I feel like it.
This is not a security camera; it's an example project, and overcomplexity is not what I want.
