feat(StakeManager): add capabilities to register vaults
This commit introduces changes related to vault registrations in the stake manager. The stake manager needs to keep track of the vaults a users creates so it can aggregate accumulated MP across vaults for any given user. The `StakeVault` now comes with a `register()` function which needs to be called to register itself with the stake manager. `StakeManager` has a new `onlyRegisteredVault` modifier that ensures only registered vaults can actually `stake` and `unstake`. Closes #70
