Refactored code to support multiple loggers, defined using "logTypes" config param. Will be easy now to add DB logging when I get around to it.
Created new logger type "excel", logs to .data file in | separated format
Changed logging routine back to every 5 seconds on suspicion that perhaps the blocking logger might have been causing some of the performance issues a few people reported on older versions of java
Added paranoidDiamonds flag, on by default. It operates the same as normal orelogging/ratios except it's only looking at the difference between diamonds. This means if someone nabs a diamond, grabs an iron ore in between and then nabs another diamond, only the ratio between the two diamonds is looked at. Also the cave algorithm and variance are ignored for diamonds. The net effect is that with this flag on, the logs are more likely to notice diamond cheaters that might have been able to fly under the radar before.
Fixed NPE bug on shutdown.
Added "flagging.flagWhenZeroLight" (default: off) which will flag events when they are being mined in zero light. Zero light does not necessarily mean a person is ore hacking, but it's does most likely mean they are light hacking (ie. they don't need torches to see in the dark).
Added counter and reasons to flags, so you will see how many consecutive flagged events a person has as well as the reasons they were flagged (ratio, lightLevel, paranoidDiamonds).
