Fixed auto-generated routes and the string representation of Route objects.
Config documentation and some more public ConfDict APIs.
Fix: run() disabling debug mode.

Changed run(debug=*) default from False to None. None does not change the current mode.
Added (untested) ConfDict.load_config(ini_file) feature.
Fix: Syntax error in templates if an {{x}} was found at the very beginning of a line and the previous line was empty.
