ZF-12218: Classmap won't be in next ZF release - update docs


As discussed during one of the IRC meetings, the ZF pregenerated classmap probably won't be part of the release, so the docs need to be updated.


    In order to use the ClassMapAutoloader, you first need class
    maps. Zend Framework ships with a class map per component or, if you grabbed the entire
    ZF distribution, a class map for the entire Zend Framework. These maps are typically in
    a file named .classmap.php within either the "Zend" directory, or
    an individual component's source directory.


Fixed in SVN r24817.
