 == Why? ==
 Autosaves currently only save "blessed" data (post_title and
 post_description?).  Plugin authors may want to add their own data in the
 autosave package so if they hook into `save_post` they can handle/save
 that data as needed.


 == How this works ==

 Metaboxes are generated with an id already on the page.  So what we do is
 add an extra parameter to the `add_meta_box()` function (`do_autosave`
 bool) so that when a plugin uses add_meta_box() they can set that flag.

 We set a javascript object that contains the ids of the metaboxes that
 have had that flag set and then `wp.autosave.getPostData` in `autosave.js`
 has been modified to loop through the metaboxes matching those ids and
 return the fields in those metaboxes as an object attached to the data
 param.

 Added a new jquery plugin (serializefullarray) as it will handle nested
 pseudo arrays set as the "name" values in inputs (i.e. somedata[one][two])
 and create proper objects from them.
