Updates macros.
 It can be passed the full path of a project. When project is not opened, this action opens it and closes it automatically.
 
 Example 1 (Selected object in GED)
 
 XGedUpdateMacroAction
 
 Example 2 (Full path of project)
 
 XGedUpdateMacroAction /ProjectName:"C:\\My Folder\\MyProject.elk"      //absolute
 XGedUpdateMacroAction /ProjectName:"C:\\My Folder\\MyProject"          //absolute without file-extension
 XGedUpdateMacroAction /ProjectName:"My Folder\\MyProject.elk"          //relative to standard-folder
 XGedUpdateMacroAction /ProjectName:MyProject.elk                                               //relative to standard-folder
 XGedUpdateMacroAction /ProjectName:MyProject                                                   //relative to standard-folder without file-extension
 
 Example 3 (Full path of project, in scripting)
 
 CommandLineInterpreter oCommandLineInterpreter = new CommandLineInterpreter();
 bool bRet = oCommandLineInterpreter.Execute("XGedUpdateMacroAction /ProjectName:\"C:\\My Folder\\MyProject.elk\"");    //absolute
 bool bRet = oCommandLineInterpreter.Execute("XGedUpdateMacroAction /ProjectName:\"C:\\My Folder\\MyProject\"");                //absolute without file-extension
 bool bRet = oCommandLineInterpreter.Execute("XGedUpdateMacroAction /ProjectName:\"My Folder\\MyProject.elk\"");                //relative to standard-folder
 bool bRet = oCommandLineInterpreter.Execute("XGedUpdateMacroAction /ProjectName:MyProject.elk");                                               //relative to standard-folder
 bool bRet = oCommandLineInterpreter.Execute("XGedUpdateMacroAction /ProjectName:MyProject");                                                   //relative to standard-folder without file-extension
 
 Example 4 (Object passed by context)
 
 StorableObjectContext context = new StorableObjectContext();
 context.StorableObject = hProject;                             //option 1: project
 context.StorableObject = aMacroBox;                            //option 2: macrobox
 context.StorableObject = hInstanceFromMacroBox;        //option 3: instance of macrobox
 new CommandLineInterpreter().Execute("XGedUpdateMacroAction ", context);
