* DataHelper, Router:
- Save config files in UTF-8 rather than the default encoding,
since we read them in UTF-8
* jetty.xml: Change encoding to UTF-8
* logs.jsp: Add system encoding
* NTCP: Clean up clock skew shitlist message
* Shitlist: Clean up expire message
* WorkingDir: Ensure modified files are processed with UTF-8 encoding
