    Revert "AGUTeX template/layout: support the new cls name"
    
    This reverts commit cde8707 and changes "AGUTeX" back to "agutex".
    The maintainer has changed "AGUTeX.cls" back to "agutex.cls" and has
    confirmed (through private email) that he plans to keep the filename
    all lowercase now that he is aware of case-sensitive file systems.
