remember the milk and RSS-Feeds / #3732

Since I had some free time I spent some hours on figuring out HTTP(s) Authentification for RSS feeds. This normally seems to be straight forwards, but there are a lot of pitfalls with different server setups. Like for me it is running in php-cgi mode.

It is still not working perfect. If the HTTP-authentification would work as expected, implementing RSS-feeds for projects should be a matter for 2 or 3 hours.

If somebody wants to speed things up, he might want to provide some help with .htaccess / mod_write (see above link).
