Multicontrollers missing some advanced options

For example, the following code from the user manual does not result in a multicontroller with a runs slider or aggregate results checkbox:
```
silentIntegrate2 = model4.integrate(silent = True)
silentSSA2 = model4.SSA(silent = True)
mc2 = mumot.MuMoTmultiController([silentIntegrate2, silentSSA2], shareAxes = True, silent = True,
initWidgets={'initialState':{'U': [1,0,1,0.01],'B': [0,0,1,0.01],
'A': [0,0,1,0.01]}, 'runs':[5,1,20,1], 'aggregateResults':True})

mc3 = mumot.MuMoTmultiController([mc2, model4.stream('A', 'B', silent = True)])
```
