New revoting about issue-#104:

The discussion

Voting for adding two new procedures Dialog.OpenExternal for opening of files and URLs and Dialog.RunExternal to run external applications.

HostDialog.Start is kept for back compatibility. There is HostDialog.hideExtRunWindow to control visibility of opened windows.

The realization with hooks is allowing easy to replace the realization for errors handling or for security issues.

Calling external applications will not break normal execution flow of BlackBox, because separate threads are used.
