Rename MsgInstantiateContract.init_funds/MsgExecuteContract.sent_funds to just funds

[webmaster128]

Both fields end up in the same structure in wasmvm, where the field name has been simplified to just funds over the last weeks. We should do that here too for consistentcy. This would also better reflect that both fields do the same thing.

• MsgInstantiateContract.init_funds
• MsgExecuteContract.sent_funds

Note this may break CosmJS - at least it would change the types in the generated ts-proto code. I guess the wire types will not change, so a version will produce tx compatible with both v0.15 and v0.16 wasmd?

Right. In SIGN_MODE_DIRECT this change is compatible. With legazy Amino JSON signing it is breaking.
