[imp] repeating icons

[Mike Barsalou]

When using the administration tool that creates the conf.php for IMP, it
creates two entries in the array for each application selected.  For
example:

what should be:

$conf['menu']['apps']=array('turba', 'kronolith'); 

is generated like:

$conf['menu']['apps']=array('turba','kronolith', 'turba','kronolith');

Now all I have to do is find where this stuff takes place and I can submit a
patch!
