Added Group Selection. You can now select multiple units and assign group orders. Group orders are mainly intended for movement (if you interact with elements that allow only a single unit to interact with them, like a cover, surrendered character, or door, only the first unit of the gruop is selected). You can select multiple units by dragging left mouse or Shift-clicking units or their unit cards. You can deselect specific units by Alt-Clicking them.
Added combat music.
Added UI sounds. These are sill limited but we plan to differentiate them more in the future.
