Enclosures should now work a little better.

Images will appear inline, now.  Unknown enclosure types no longer default to being described as podcasts.
Skip embedding any empty enclosures, not just images.
Merge branch 'fix-enclosures'
Cleanup of enclosure fixes.

Don't display enclosed images by default.
Don't overwrite article title with enclosure titles.
Each enclosure and corresponding display handle now in its own div.

Merge pull request #5 from plaidfluff/master

Added item_author column, ability to autotag based on author.
Agnostified sql for adding item_author column.

SQLite was unhappy with column specification.
Format/comment fixes
Quieted warnings in fof_update_feed() when feed items lack authors.
Reimplemented 'delete tag from all items' action to not use all of the memories.

Added fof_db_untag_user_all() to fof-db.php, which simply removes all occurrences of a tag for a user.
Changed fof_untag() in fof-main.php to use this function instead of generating a list of tagged items and then removing that tag from those items.  The old method worked for a handful of items, but was using a ridiculously unnecessary amount of memory when trying to clear a tag from a few tens-of-thousands of items.
Clean up some logic around tag plugins
Add permalink to bottom bar, for easier post-item-reading opening
Most languages: Oh, I'll return an empty array, and foreach will just be a
no-op. PHP: Oh, I'll return a null value, and foreach will shit a brick.
