Parameters v4

The parameters below represent the parameters for app version 4.

Note that not all of these parameters are changeable via governance. This list also includes parameter that require a hardfork to change due to being manually hardcoded in the application or they are blocked by the ParamFilterDecorator. Parameters that are governance modifiables can be modified via a MsgSubmitProposal that contains a moduleXYZ.MsgUpdateParams message.
