seedwatch can't handle pomegranate seeds

pomegranates are trees, and so pomegranate seeds are tree seeds; seedwatch doesn't do anything for tree seeds because tree seeds are not plantable and so there is no purpose in retaining a stock of them

the reason it reports that "POMEGRANATE has not been found as a material" is because it's looking for a plantable seed and pomegranate seeds are not plantable. there might also be something weird about pomegranates in the raws here, need to research this further

so this is WAI except perhaps that seedwatch should simply not mention tree seeds at all since it has nothing useful to say or do about them anyway, which i thought we had done but apparently while we fixed it in one place we missed it in the other
