Documentation updates for hybrid-media-meta.php.
Always load the Hybrid Media Grabber.  No longer a need for add_theme_support( 'hybrid-core-media-grabber' ).
Correct inline documentation in hybrid-media-grabber.php.
Update the hybrid.php inline documentation. Introduce Hybrid::includes() and drop Hybrid::functions().  Make sure files are loaded at more appropriate times so that theme authors have more functionality available on the 'after_setup_theme' hook.
Allow theme developers to change the directory path and directory URI of the Hybrid framework folder.
