Better support for normal log-in behaviour

First Timer is great, however it appears that on subsequent log-ins that having First Timer enabled prevents behaviour such as 'return to previous URL after log-in' in modules such as 'Free Member'.

It appears that changing line 147 to:

`else if ($this->settings['normal_redirect']!="")`

solves the problem by allowing the 'normal redirect' value to be ignored if not set.
