* 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
- Make IRC Proxy non-shared, delayed-start, close-on-idle
for new users, for the anonymity benefits (see "Shared Clients,
Correlation and Collusion" http://zzz.i2p/topics/217 )
- Remove "experimental" flag on new client options
* configclients.jsp: Add full path to config file
* Add some path help in some config files
