Multiple Post Thumbnails

Version Description

Add a size parameter to MultiPostThumbnails::get_post_thumbnail_url to allow getting any registered size.
Add context option to the args accepted when instantiating a new MultiPostThumbnails to specify the metabox context. Defaults to side (which it was previously hard coded to).
Filter is_protected_meta to hide meta from the Custom Fields metabox by default (props willroy). To unhide them, add add_filter('mpt_unprotect_meta', '__return_true'); to your theme's functions.php.

112	+ * Filter `is_protected_meta` to hide meta from the Custom Fields metabox by default (props willroy). To unhide them, add `add_filter('mpt_unprotect_meta', '__return_true');` to your theme's `functions.php`.
