Subject: Add configuration option "$ITEM.SINGLE_REDIRECT"

Each option can be set to "TRUE" or "FALSE" (the default value is "FALSE"). For example, if you only have one user and "USER.SINGLE_REDIRECT" is set to "TRUE", then requests to "/user/" will be automatically redirected to "/user/username/".
