Added WVR. All the guides are done, but I'll refine them later when more data is available.

Soon, once prices stabilize a bit more, I'll plug the seemingly cheapest desynth items for each type of demimateria into a spreadsheet of mine and get the actual costs on my server. Doesn't help other servers, but hey, at least it's some method of comparing the items! We need what, 80x Fieldcraft Demimateria Is for all the new DoL/DoH accessories, plus 110x Fieldcraft Demimateria IIIs for the new tools? So, yeah, I can definitely see finding the cheapest ways to get them to be useful to know.
