openTCS配置log文件路径

运行debug plantoverview时会找不到log路径，报错：

通过断点查看到当前目录是E:\OpenTCS\openTCS-4.18.0-src

默认的配置是

所以组合出来的完整路路径是，E:\OpenTCS\openTCS-4.18.0-src\.\log\opentcs-plantoverview.0.log.lck 这个是不存在的，所以报错了。

解决方法：

把logging.config配置改为

java.util.logging.FileHandler.pattern = openTCS-PlantOverview/build/install/openTCS-PlantOverview/loglog/opentcs-plantoverview.%g.log

就可以获取到正确的log路径。
