Update Scheduler Title when StartMonth changes in Year Views

[paulo-rico]

This is in response to our conversation earlier in the week where the Change event was behaving differently in a couple of controls.

Because the StartMonth property is only applicable to 'Year Views' and is not in the Parent Scheduler component, the Title doesn't automatically update.

So I've implemented it in the same way that forces the Reload of the Scheduler in the SchedulerViewBase when the Title changes. But I've put it in a derived SchedulerYearViewBase that will react to a change in StartMonth.
