Properly Document GRAYCE Integrations

[Caervec]

There are numerous changes under the hood to mods in the GRAYCE tree intended to make them beholden to Thaumcraft. These changes are hidden and utterly impossible for a user to know about.

Make them known, whether it's through a quick patchoulli manual, tooltips, or guidance in the skill trees, but however it's possible get it done.
Ideally, rewriting the Thaumonomicon and EB Wizardry manuals to reflect this information via resources would be ideal, but may not be possible.
