Convert the supports system into shards as well

LLohm

I will sincerely like to the thank the devs and D3 for listening to us with regards to the revision awarding of shards for feeder 5* this has been greatly appreciated.

We do have a lot of 4* left that is not feeding any 5* at the moment and I thought it would be nice if we can chase after supports via the shards extension if they implement it to supports.

I hope this will be considered. Thanks
