Consider adding an Include directive to config files

[pepone]

I think will be nice to have a Include directive that allow to split configuration files:

#
# IceSSL Configuration 
#
Include config.IceSSL

#
# Uncomment the following line to include the Logger Plug-in configuration
#
#Include config.LoggerPlugin

For the syntax, I would use include = filename, like https://commons.apache.org/proper/commons-configuration/userguide/howto_properties.html.
