CodeSnip Old Code (SVN)

* Switched off support for Vista common dialogs in UCommonDlg.pas for compilers that support these dialogs.
* Added SupportsUseLatestCommonDialogs symbol to CompilerDefines.inc that is defined for compilers where Dialogs.UseLatestCommonDialogs is declared.

* Replaced call to deprecated TThread.Resume method in TThreadWrapper.DoExecute and TWaitForActionUI.Execute with calls to TThread.Start on Delphi 2010 and later compilers.
* Added ThreadResumeDeprecated symbol to CompilerDefines.inc that is defined for compilers where TThread.Resume is deprecated.

New include file, CompilerDefines.inc, that defines symbols used to conditionally compile code that is dependent on compiler version.
