Note:

How autoloader resolves ext_autoload files for a given class name (I 
debugged this some weeks ago):

- Autoloader is called with some class name
- If class name is not in 'already loaded, merged ext_autoload array' 
and not in (always loaded) core_autoload array:
- "Guess" extensionname from class name (basically split 
'tx_extname_class' to 'extname' only)
- Load extname/ext_autoload.php if exists, merge with existing lookup array
- Look up class name in array, return path if exists, else error.
