Screen: Virtual methods for SDL and window resize events

The `Screen` abstract class now provides virtual methods for SDL and window resize events. The `Editor` and `PartcleEditor` classes now `override` the `event(const SDL_Event& ev)` method and `Editor` `override`s `on_window_resize()`. Resize events in `ScreenManager` are now handled by all `Screen`s in the stack. SDL events are only handled by the current (top) screen. Additionally, `OptionsMenu` now calls `ScreenManager::on_window_resize()` on video setting changes, instead of just calling `MenuManager::on_window_resize()`. This fixes a bug where the editor crashes on changing the "Video Resolution" and "Magnification" settings from the in-editor "Options" menu.
