[TYPO3-mvc] There's a typo.. somewhere

[Sebastian Gebhard]

Hi,

I found a little issue but don't have time to investigate it right now. 
I took a look at Tx_Extbase_Dispatcher::getSettings(); and saw there:

  [interfaces] => Array
         (
             [Tx_Extbase_Persistence_Storage_Backend] => Array
                 (
                     [implementations] => Array
                         (
                             [1] => Array
                                 (
                                     [className] => 
Tx_Extbase_Persistence_Storage_Typo3DbBackend
                                 )

                             [2] => Array
                                 (
                                     [className] => 
Tx_Extbase_PErsistence_Storage_PdoBackend
                                 )

                         )

                 )

         )

There's a typo at the class name of the PDO Backend.
