Use enums from KIconLoader

Instead of using hardcore numbers, it would be great to use the enums provided by 
KIconLoader whenever we use sizes for icons.

Made the change for the obvious ones replacing "16" by KIconLoader::SizeSmall, 
"22" by KIconLoader::SizeSmallMedium and "32" by KIconLoader::SizeMedium.
