Subject: made TJuiControl options changeable during callback

- TJuiControlOptions are now stored in viewstate and tracked by the new
TJuiCallbackPageStateTracker class extending the default viewstate
tracker class
- TJuiCallbackPageStateTracker registers endscripts automatically for
each changed option for the clientside changes, added some normalized
getter for that
