Current behavior

Hide the following buttons from the menu bar when the model configuration/simulation perspective is active.
Hide cut, copy, undo, redo paste

We can hide these buttons because there is not elements to copy or paste under this perpective. In addition, currently undo and redo options are only available for modeling functionalities, then on this perspective are useless

Environment
