Remove pages from the RSS feed (readme)

This commit removes the pages from the RSS feed. I decided so because a
page is a "timeless" object intended for things like the imprint, about
page, privacy policy and similar stuff. It also makes things easier.

The new primary feed URL is "/feed/" and shows only posts. The page feed
("/feed/page/") has been removed and will throw a 404 Not Found error.

The visitors who already subscribed to the old post feed ("/feed/post/")
are automatically 301-redirected to the new location ("/feed/").

The following system language variables have been removed:

* feed_name_items
* feed_name_pages
* feed_name_posts

The following configuration options have been removed:

* PAGE.FEED_SIZE
* PAGE.FEED_SORT
* PAGE.FEED_GUID

Furthermore, the template file "feed/item_post.php" has been renamed to
"feed/item.php" since there is now only one type of feed item. If the
system cannot find the "feed/item.php", it tries "feed/item_post.php"
instead (for backward compatibility with older themes).
