## Description
This PR adds a `ModuleDB` interface which can be used directly by Cosmos SDK modules. A simplified bank example with Mint/Send/Burn functionality against Balance and Supply tables is included in the tests.
This PR also:
* adds simplified `Get` and `Has` methods to `Table` which use the primary key values in the message instead of `...interface{}`
* adds a stable deterministic proto JSON marshaler and updates the `Entry.String` methods to use it because the golden tests are not deterministic without this. This code is currently internal but can be extracted to a public `codec` or `cosmos-proto` package eventually.
