Subject: [PATCH] client: add FontSelector SettingsPage::hasChanged

Add support for FontSelector in SettingsPage::hasChanged(), allowing
one to easily test if a specific font selector has changed since last
save.

This allows for optimizing stylesheet updates to only happen when
relevant settings are changed.
