[Lazarus] TApplication.DoubleBuffered

[AlexeyT]

   TApplicationType = (
     atDefault,     // The widgetset will attempt to auto-detect the 
device type
     atDesktop,     // For common desktops and notebooks

   TApplicationExceptionDlg = (
     aedOkCancelDialog,  // Exception handler window will be a dialog 
with Ok/Cancel buttons
     aedOkMessageBox     // Exception handler window will be a simple 
message box

so its logical to name new TApplicationDoubleBuffered values with "adb" 
prefix.
