Options: tabs Allgemein / Beute / Tastenbelegung with key bindings

- Options window in three tabs; the auto-pickup settings move to Beute;
  sliders move with their page; black sides like the save game screen.
- Tastenbelegung: every binding settable (click, press key; Esc cancels,
  Backspace unbinds), "Alle zurücksetzen" as a game button, saved on OK.
- Potions bindable (default unbound), named by the game's potion texts; the
  game's own potion hotkeys are off; bar tooltips show the bound key.
- Map (M), overview map (Tab, held) and labels (Alt, held) bindable; the
  game's own M / Tab / Alt handling is switched off.
- Save game key calls the game's save window code instead of a posted key.
- Teleportationstrank: fixed text replacement from startup (also the
  Ausdauertrank items, potion kind 5 as well).
