Report immature coinbase transactions in listtransactions

Report coin generation transactions as 'category':'immature' until they have 120 confirmations (when they are reported as 'category':'generate', as before).
If the block they are in is not part of the main chain (you lost a 'block race'), then they are reported as 'category':'orphan' (with 0 confirmations).
