Remove of hardcoded sound effect references in MenuManager

- A small refactor of menu/menus.txt loading to support specifying open and close sound effect for each menu.

- Updated default/menu/menus.txt to the new definition format of menus.

- Removed responsibility for sound effect playback from closeAll() closeLeft() and closeRight() and added playback of menu specific sound effect at spot.

- Remove of hardcoded coins and loot sound effects, see commit 84d2aae
