bn9 QoL improvements

Increased BN multipliers for HacknetNodeMoney and WorldDaemonDifficulty to PI (3.14159...). This brings WD required hack to 9424.77796076938 (now the 2nd highest ^-^).
Bn9 now starts with the same node bn9.3 rewards (the idea here is it helps showcase the BNs new feature and just speeds up a lot of what made it so slow early on)
