Update RSS generation function.

If you create a post with a future date of publish, this appears in RSS.

This modification of Blog.php file solves the problem, but there are some things to improve:

1. The RSS only updates when create, modify and save any post.
   
2. So, when deleting a post, it remains on RSS feed
   
3. So, you can publish any post with future date and it will neve be included on RSS feed until you create or save any time
   
4. It will be a better solution to allow rss feed to be a dinamic PHP instead a single generated file... this will solve all the bugs
   

Here the Blog.php code for RSS feed generation:

PHP Code:
