 * Hotkey system.
 *
 * Hotkeys consist of a name (an arbitrary string), and a key mapping.
 * The names and mappings are loaded from the config system (any
 * config setting with the name prefix "hotkey.").
 * When a hotkey is pressed or released, SDL_HOTKEYDOWN and SDL_HOTKEYUP
 * events are triggered, with the hotkey name stored in ev.user.data1
 * as a const char*.
