Comment Parsing

Implements comments by adding two different functions..

/**
 * Gets a list of video comments from the specified feed and returns them as comment objects.
 *
 * @param $feed
 *   The URL of the comment feed you want.
 * @param $start_at
 *   The record to start at.
 * @param $num_comments
 *   The number of comments to return.
 *
 */
$comments = youtube_api_get_comments($video->comments['href'], 1, 25);

/**
 * Parse the returns of a single comment entry from the XML feed and return it as an object.
 *
 * @param $entry
 *   The simpleXML object for a comments entry record.
 *
 */
$comment = youtube_api_get_comment_object($entry);

Probably still needs to include the ability to load comments along with videos from video searches, loading a video directly, user feeds, etc.

Thoughts?

Now with a fresh theme function, and an optional parameter to theme_youtube_api_embed to load/display comments for a given video.

I've shelfed the idea of having loading comments be an optional parameter to the functions for video feeds, as making that many successive calls to the API is _slow_. May revisit later.
