Allow for serving feeds from a separate domain.

This (indirectly) enables support for FeedBurner. Added docs for FeedBurner configuration. Clarify how defining the SITEURL attribute affects URL structure. Closes getpelican#177.

+FeedBurner
+----------
+
+If you want to use FeedBurner for your primary Atom feed, there are two
+primary fields to configure in the `FeedBurner
+<http://feedburner.google.com>`_ interface: "Original Feed" and "Feed Address".
+If using the default Pelican `FEED` attribute and assuming your feeds
+are served from the `www.example.com` domain, you would enter
+`http://www.example.com/feeds/all.atom.xml` in the "Original Feed" field in
+FeedBurner.
+
+For the "Feed Address" field in the FeedBurner interface, you may choose
+whatever suffix you prefer. In your Pelican settings, assign this suffix to
+the `FEED_MAIN_URL` setting. So if your FeedBurner feed address is set to
+`http://feeds.feedburner.com/myblogfeed`, in your Pelican settings you would
+set: `FEED_MAIN_URL = "myblogfeed"`. Then set the `FEED_DOMAIN` setting to
+`http://feeds.feedburner.com`, or `http://feeds.example.com` if you are using
+a CNAME on your own domain (i.e., FeedBurner's "MyBrand" feature).
