Replace get_category_rss_link with get_category_feed_link

[ionfish]

Replacing get_category_rss_link with a get_category_feed_link function would allow theme authors to use WordPress's Atom feeds instead, if they prefer. get_category_rss_link would be deprecated, but not removed, to keep backwards compatibility with themes which use it.

+1 on the idea. But the patch only addresses default permalinks. People with pretty permalinks wouldn't get the feed type they asked for.

Good point. I'll tweak the patch. I was also thinking of doing the same for get_author_rss_link, should I add that to this ticket or make a new one?

Look at get_tag_feed_link() and pattern get_category_feed_link() after it. We don't really need to pass the nicename and echo.

More like it? :)

Getting better. On line 150, you need to trailingslashit($link) (like on the old line 138). Otherwise, you could get:

 http://example.com/category/foofeed/atom

Any chance of another look-over?
