[tor-commits] [flashproxy/master] Use an iframe for badge embedding.
commit 36d0773ee9197c992819d1fbbb1b63e95e298921

Use an iframe for badge embedding.
Dan told me: "Sites will likely want to iframe the script so as not to
give it control of the enclosing page." This makes sense. So provide a
public embed.html, and add a sample iframe HTML snippet to easily
include it.

Paste in this HTML where you want the badge to appear:
