Post Metaboxes Tabs

When you have a lot of metaboxes in the post/page edit screen, you end up scrolling which is confusing. Metaboxes
represent a group of fields like Address, or Ingredients, etc. Imagine you are creating a deep CV for a person.
Suddently you have Addresses, Contacts, Profile, Education, Skills, Languages, etc. But as you can see
Addresses, Contacts, Profile can be categorized as `Personal Data.

This plugin lets you group metaboxes by anything, just name each metabox as Tab / Box name. So the
Addresses metabox should be named as Personal Data / Addresses and it will be grouped with Personal Data / Contact
under Personal Data tab.

Notes:

• Both Tab / Box name and Tab/Box name or Tab/ Box name work
• Built-in metaboxes are ignored (they usually sit in the sidebar and are needed all the time)
• Although tested on 3.2, it should work since 2.5
• Javascript enabled is required
