Splitting up the settings file to private/public parts (issue #99)

I added comments and a settings.ini.proto so new upcoming testers will understand how it looks like, and/or rename/use and change it to fit their test server config

I also added:
```
if configFile == "":
    print "WARNING: You need to set a path to the config file, see settings.py"
```
not sure if it will be necessary but I think it's a good reminder when switching to production mode
