This will allow to use this everywhere !
Before this commit we had :
UiContentBlock
aCSSClasses
GetCssClasses
SetCssClasses // reset + add, existing callers
AddCSSClasses
Button
$aAdditionalCSSClasses
GetAdditionalCSSClass
AddCSSClasses
Now we have :
UiBlock
aAdditionalCSSClasses
AddCSSClasses
SetCSSClasses
GetAdditionalCSSClass
Note that there were also some methods in PopoverMenuItem :
PopoverMenuItem
SetCssClasses
AddCssClass
GetCssClasses
As they are indirection to methods in the $oPopupMenuItem attribute, I added to them the "MenuItem" prefix :
SetMenuItemCssClasses
AddMenuItemCssClass
GetMenuItemCssClasses
Didn't find any use to change.
