MasterKey, / MasterChest

[Flavourized]

So the first part of this feature directly affects keycrates (as opposed to Mystercrate). The feature would let us make sure key which we can use on multiple crates. There would be the normal keys for each of those crates, but this key would be separate.

Next part is basically doing the opposite of above. It would allow us to use multiple keys on the same chest.

E.G

MasterKey1 opens crate1 MasterKey1 opens crate2 masterKey1 does not open crate 1

Crate1 opened by Key1 Crate1 opened by Key2 Crate1 opened by key3
