Returns: AC_FAIL: There was not enough room in the operation history for the action and the user did not wish to continue. Usually End() should be called in this situation.

Purpose: To check that there is sufficient room for the action in the operation history, and if there is, then to add the action to the operations action list. The function calls the Action::Init function passing the runtime class of a CopyObjectsToClipboardAction.
