[horde] H6 imp appears to ignore mime_drivers.local.php

The new version will be released shortly. There is a bit of a problem 
here which put this on delay. It might happen that the autoloader tries 
to load the hooks.local.php class twice. You can prevent this by putting 
your custom hook class into a phrase like this:

https://github.com/horde/whups/blob/FRAMEWORK_6_0/config/hooks.php.dist
if (!class_exists('Whups_Hooks')) {

     class Whups_Hooks  {

      ...

}

}

This is only a problem with classes but not with config files which only 
contain arrays. I've described this chain of issues in more details 
here: https://www.ralf-lang.de/2025/05/27/a-wicked-problem-from-the-past/
We will release versions of the apps and libraries with restriction 
rules for the autoloaders to prevent this from happening in the first 
place.
