Follow Blogs: Change all tab names to "Followed Sites".

Previously, a mismash of terms were used - "Sites I Follow" and "Followed
Blogs".  Stick with "Followed Sites" for consistency with BP core.

See #31.
Add RSS feed for followed sites.

By default, feed can be located at:
example.com/members/USERNAME/activity/followblogs/feed/

See #31, #6.
Follow Blogs: Set the "RSS" feed URL on the Sitewide Activity page.

When the "Followed Sites" tab is clicked on the activity directory page,
this commit changes the "RSS" link to the user's Followed Sites RSS feed.

See #31.
Follow Blogs: Change "Home" button to "Followed Sites".

See commit 152aa8c.
Follow Blogs: Set 'block_self' parameter to false in follow button.

There is no reason why this should be true.
Follow Blogs: Add a new conditional method to show the footer buttons.

By default, the footer buttons are shown all the time, but if we're on the
BP root blog, the footer buttons are only shown when on a blog page.

Might tweak this a bit later on.

See #31.
