Problem with dateChoose in v8.3 Pro

Experimented on latest version 8.3 Pro

Browsers : Chrome, IE10, Firefox

I found some changes for style on date pickers between Isomorphic 8.3 and Isomorphic 8.2.
The style name for days that we can’t select (because they belong to prev/next month) :
• dateChooserWeekendDisabled in 8.2 became dateChooserDisabledWeekendDisabled in 8.3
• dateChooserWeekdayDisabled in 8.2 became dateChooserDisabledWeekdayDisabled in 8.3

There is another problem for headers and bottom’s button, because their own styles have disappeared in 8.3 :
• dateChooserButton and dateChooserWeekendButton in 8.2 became headerTitle in 8.3
• dateChooserBottomButton in 8.2 became buttonTitle in 8.3
