thunder2 e95725ea2c - Fixed crash because of a memory overwrite
The static arrays in RsDiscSpace were to small for RS_PGP_DIRECTORY (0x0003)
  Added new constant RS_DIRECTORY_COUNT
- Added missing fclose to PGPHandler::encryptTextToFile
  Used ops_teardown_file_write instead of ops_writer_close and ops_create_info_delete
  Windows cannot move a file when it is still open
