/v2/items/:id missing new EoD flag for Research Kit salvage

[Keorl]

There is already a NoSalvage flag, but the api doesn't have the separate flag for salvage with Research Kit.
Given that this flag is now fairly inconsistent (contrarily to its release description : anything that is crafted) and can change with each patch, having it in the API would let community tools provide lists of items that can be salvaged for Research Pages.
Also, it would be great to have the research loot table for each item where applicable. It would make it possible to calculate possible returns at any given time. Again, it changes with patches and there are thousands and thousands of items so community research can simply not follow.
Together, those API changes would make it possible to provide tools for players who need research pages, and would drastically ease the very bad perception of this new system.
