Bonus Chest as Ender Chests with starting loot

There should be an option for Bonus Chests to behave as Ender Chests, so that when multiple players begin a new world, each person gets their own Bonus Chest loot. The loot could be generated to be the same for everyone, or maybe each person gets their loot generated separately. So the possibilities for this gamerule would be:

* same loot (Bonus Chest generates the same stuff for everyone, and the Bonus Chest acts as a starting Ender Chest in the world)

* different loot (as above, but Bonus Chest generates different starting items for each player)

* shared loot (how things currently work now with Bonus Chest enabled)

* no loot (no Bonus Chest at all).

We are also assuming no one joining the game is going to be a jerk by going off and breaking the Bonus Chest so no one else can benefit. But I would like to suggest Bonus Chests be made an actual block with their own ID and be indestructible. As well, most players do not really need a chest to start play with since they can get wood to make one (notwithstanding unique limited resource scenarios).
