/*
 * Improve ButtonWidget
 * - added button highlight
 * - some properties can be editable outside (ButtonNameFontSize, ButtonBoundsWidth, ButtonBoundsColor...)
 * - integration of highlight with HintManager (HintManager->OnHintActivated)
 * - the change of properties displayed in the blueprint
 * - integration of highlight with StoryManager (StoryManager->OnNewStep, StoryManager->OnNewSubStep, StoryManager->OnStoryLoaded)
