Show Modname in logfile

[taubenangriff]

Especially for bugfixing it would be incredibly helpful if you get the Name of the mod shown in the logfile for each Warning that gets printed.

So instead of this
[2019-09-14 13:36:56.558] [warning] No matching node for Path //Asset[Values/Standard/GUID='192069']/Values/RewardPool/ItemsPool/Item[ItemLink = '193739']

You would get something like this:
[2019-09-14 13:36:56.558] [warning] Modname: No matching node for Path //Asset[Values/Standard/GUID='192069']/Values/RewardPool/ItemsPool/Item[ItemLink = '193739']

Yes, the code is already kind of in there but forgot to put it in for those warnings, will do that later tonight
