final look and feel

[tgianko]

Below is a draft of how Fidelius should look like.

The overlay server should always show the green horizontal bar. The "pay.site.com" is created by the enclave and sent to the overlay server as usual. The rest of the bar and the text in it, e.g., Fidelius active/inactive, is added by the overlay server. When an origin is present, then fidelius is active, otherwise is inactive.
