Update filter hook names to use the 'hybrid_' prefix.
Use the 'TextDomain' header set in 'style.css' to get the proper textdomain.  If not set, fall back to get_template() and get_stylesheet().
No need to pass parameters to wp_get_theme() when dealing with the stylesheet (child/active) theme directory.
Add the Hybrid Media Grabber script for fetching media related to the post.  This script is for getting media embedded into the post content in various ways (shortcodes, HTML, autoembed, etc.) or getting media attached to the post.  It consolidates all methods of using audio/video media in posts that WordPress currently supports as of the current trunk.
