RSS feeds for BP activity have historically been generated on a one-by-one basis, with separate template files used for each theme. This resulted in a huge amount of unnecessarily duplicated code. Moreover, it made the process of customizing feeds, or providing new feeds, unnecessarily cumbersome. BP_Activity_Feed abstracts the central parts of RSS feed building, allowing for easier customization, and fewer points of failure. This changeset also fixes our RSS implementation to match best practices with respect to encoding content inside of the <description> element. Fixes #5020 Props r-a-y git-svn-id: https://buddypress.svn.wordpress.org/trunk@7207 cdf35c40-ae34-48e0-9cc9-0c9da1808c22
