[imp] require_once inside of functions are dangerous

[Jan Schneider]

Zitat von Earnie Boyd <earnie at users.sourceforge.net>:

> Maintainers please take note:
>
> When using require_once for things like IMP_BASE .  
> '/config/header.php' and the file has been included once already the  
> second occurrence causes the $_header array to not be defined and  
> errors are issued to the user.  I changed line 133 of  
> lib/MIME/Headers.php substituting "require_once" with "require" to  
> resolve the issue.  I only noticed the issue when reporting spam.   
> Please excuse the lame report; I don't have time to chase a proper  
> patch (the usual cry from users).
