Json assets Json assets doesn't add the seeds in the shop

[tsubasachan]

Json assets doesn't add the seeds more automatically in Pierre, and neither manually by putting "SeedPurchaseFrom" : "Pierre" << that doesn't work either, neither automatic nor manual.

To temporarily solve the problem I'm adding using the shop tile framework, has json assets removed this function?

Fixed somewhere around #429 (partly by that PR, probably partly by some related commits by Casey).
