* AliEveEventManager
  Add support for automatically finding appropriate raw-data file when
  connecting to a centrally reconstructed run in alien.
  This is enabled by calling a static function:
    AliEveEventManager::SearchRawForCentralReconstruction();

* macros/visscan_raw_raw.C
  New wrapper macro -- enable SearchRawForCentralReconstruction().

One can now do:
  alieve visscan_raw_raw.C'("alien:///alice/data/2009/LHC09c/000101134/ESDs/pass1/09000101134018.10")'
and both reco and raw will be available.
