Added language splash screen updates... there was never an Italian splash screen so I just duplicated the English splash screen with the "_it" ending (it previously used the English splash screen too).
Moved "To plot or export simulation results, open the <b>Plot / Export simulation</b> dialog by double-clicking the <b>Simulate & Plot</b> button in the lower right-hand corner of the <b>Edit simulation</b> dialog (next to the <em> Close</em> button)." to prior screen so as to not over-run the dialog window... it seemed like that's where it belonged anyway.
