too many pages say ANNOUNCE_RSS="yes"
It results in a line inside <head> that says
```
<link rel="alternate" title="Tor Project OR-announce" href="http://rss.gmane.org/gmane.network.onion-routing.announce"
type="application/rss+xml">
```
Which page is *supposed* to have this? The front index page? The download page? None of the above?
It's in a bunch of pages, like the arm project page, the sample project page, the Torbutton index page, etc.
