Various bug fixes for Dragonflight (#759)

This CL fixes the addon not loading for users and eliminates most errors so the Addon is usable. This CL does not add new features or support for the new bag type in Retail, yet. A set of more comprehensive updates will be released at a later date.

* Fixed a nil value bug in ItemLevel.lua

* Updated docmeta

* Fixed bug that caused item borders not to update.

* Updated config TOC
