Document in HTML how and why to enter this mode.

I have revised the HTML page.
I didn't do it because I was thinking that we might not want to explicitly talk
about Flash-private feature in the example page. But with a second thought, I
think it is okay to do so. (Of course, we should not do this in the NaCl
example.)
