New NPCServer: Less memory usage

[Admins]

A new npcserver has been uploaded to all machines, Era and Unholy Nation has already been restarted. We have fixed a few smaller memory leaks and changed some stuff to use less memory. There are also a few new commands to be able to manage memory usage better:

Script:
getProcessCPUUsage() - returns float - CPU usage of the game/server (0-1) in the previous minute, multiply with 100 to get a percentage
getProcessUptime() - returns integer - total number of seconds since the game/server started
getMemoryUsage() - returns integer
getMemoryStatsObjects() - returns integer - returns the total memory taken by objects, beta (like /memstats)

RC chat:
New commands to analyze the memory usage of script objects and levels, this not very exact right now but can be used to find npcs which take a lot of memory:
/memstats
/memstats full
/memstats npc name
/memstats level name
