enabling contract owners to pay transaction fees on behalf of users

[maxxkrypto]

For Fragmented Soul we plan on distributing our governance token entirely in game. This will be done via game progress, quests, and incremental achievements. We would like to figure out some way to make it so that we can provide the stamp cost for the transactions that will be distributing FSG (fragmented soul governance) so that players do not need to pay in order to receive these tokens. thank you!
