Add RSS icon somewhere and promote the RSS feed

[oparoz]

It's really nice to have an RSS feed, but it's not promoted anywhere and not clearly visible on the frontpage.

• [ ] Add a description on the homepage about the possibility to stay up to date
• [ ] Add a RSS button on the homepage
• [x] Add a RSS feed for each app
• [ ] Add a RSS button for each app

Bottom of the page should probably contain a Feeds link which lists all feeds (you can include prereleases and nightlies as well).

A fully filtered RSS feed looks like this:

http://127.0.0.1:8000/de/feeds/releases.rss?app=news&nightly=true&prerelease=true

A feed for an app looks like this:

http://127.0.0.1:8000/de/feeds/releases.rss?app=news

A non filtered feed for everything looks like this

http://127.0.0.1:8000/de/feeds/releases.rss

A filtered feed for all releases looks like this

http://127.0.0.1:8000/de/feeds/releases.rss?nightly=true&prerelease=true

Depending on the ending (.atom or .rss) you can choose the type.
