Savings module scaffold (#1188)

* module files

* proto types

* types and generated proto types

* keeper

* client scaffold

* add savings module to app

* remove placeholder types file

* implement rest and add to module

* update comments

* remove unused imports from proto files

* remove abci

* remove refs to other modules

* remove endblocker call

* genesis init test for module account
