Added code to keep track of gold in the world.
Handling gold addition messages.  Additionally, changed several channels to be buffered so that do not block when wrie into them and get into a case of deadlock.
Two primary changes: #1 Capitalized several members of message structs so that json would serialize them; #2 had forgotten to add new gold stashes to gold map: fixed.
Tracking and forwarding all plant messages to users.
