Package trace config

[blam23]

Having the option to enable trace logging to file would be useful as an option in GUI.

Currently it is handled via the .config file, example attached (remove .txt extension to use).
Janus.exe.config.txt

Attached config is same as:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1"/>
    </startup>
    <system.diagnostics>
      <trace autoflush="true">
        <listeners>
          <add name="textListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="trace.log"/>
          <remove name="Default"/>
        </listeners>
      </trace>
    </system.diagnostics>
</configuration>
