Let the video shortcode accept a YouTube URL as the value of its `src` attribute, as MediaElement.js supports Chromeless YouTube videos by using a pseudo-mime-type `video/youtube`. 

HTTP and HTTPS www, non-www, and short url fronts are supported:
http://www.youtube.com/watch 
https://www.youtube.com/watch
http://youtube.com/watch
https://youtube.com/watch
http://youtu.be
https://youtu.be

Remove `$force` argument from `WP_Object_Cache::delete()`. From @nacin: "This was for internal-use-only, I don't think _deprecated_argument() is needed, but let's put a comment somewhere just so we know we'd have to be careful if we ever want to add a third argument here later."

`$force` argument has been removed, and docs were updated.

Ensure compatibility with MySQL 5.6 which has stricter SQL modes by default.

Disables NO_ZERO_DATE, ONLY_FULL_GROUP_BY, STRICT_TRANS_TABLES, STRICT_ALL_TABLES, TRADITIONAL. Introduces wpdb::set_sql_mode() with an incompatible_sql_modes filter so a plugin can alter the set mode after the fact.
