[development] Saving admin settings

[Jeff Greenberg]

Lately, it seems that I'm stumped by what turns out to be 'weak eyes.'  
Here's another. I have a callback to the function in a module that 
provides the admin settings form for the module.

The form appears just fine, and functions correctly. At the end of my 
form definition I have the obligatory

    return system_settings_form($form);


The issue is that none of the form data is stored. The form is 
generic...no submit handler specified.
