Added environment variable expansion to the command line handling of desktop actions, plus the special '%AlfrescoDir%' token for the

current working directory path (from the client side).
Updated sample commandline test action to use '%SystemRoot%\Notepad.exe'.
Added lock check to check out action code to give more meaningful error message.
