* Add authority, MsgUpdateParams

* Add e2e test for x/community UpdateParamsMsg proposal

* Ensure new params are different

* Add errors and update codec

* Update changelog

* Use single reused govAuthorityAddr

* Add unit tests for authority and msg

* Validate authority address

* Update proto comment

* Check for ErrInvalidSigner in invalid authority error
