The FeedWriter class is now abstract, which means it is not possible to directly create an instance of it. Use the new wrapper classes in FeedTypes.php instead. This also obsoletes the constructor's version parameter for end-users.

* Only accept instances of FeedItem
* Only accept instances of FeedItem with the same feed type

* Fixed spelling mistakes
* All \n's were replaced by PHP_EOL's

require_once -> require due to APC issues

APC shouldn't have to open files more than once, but it does if you use require_once instead of require. More details here:

The minimal example should have minimal requirements...

This time using htmlspecialchars instead of htmlentities, because we need a encoding for XML, not for HTML.

So this has now not to be done by the user. Another benefit of this change: The examples do work now. ;-)
