Notes:
- array_flip method deprecated for delete item detection.
- using form handler is deprecated and present only for backwards compatibility.
- using generic terms like EDIT and DELETE in Language file is deprecated, use LAN_EDIT etc. instead.
- using terms like created, update, options etc..deprecated should use built in terms.
- generic admin icons used. ADMIN_ICON_EDIT etc.
- using $caption = "whatever", is unneccessary.
