[Feature] Gem bubbling.

[apuel]

When a player is poofed, another player should be able to find and bubble them. What this means? Dunno, but it could work similarly to how the old code did it (Spawn a colored glass entity, put the gem inside, let the player carry them around until it pops and they reform).

Sending the gems somewhere might be nice as well, but this could be dicey. Needs to be discussed more.
