Finish and clean up module queries and txs (#152)

* Basic transactions set up (to be separated)

* Change transaction command to not include create operation (to include other command in next commit)

* set up create command and made minor changes

* wip implements module queries

* Added tests for query address decoding

* Added ambiguous encoding of to address in transaction and added tests

* Fix linting issue

* Move registering key types to application level to allow module usage to ignore

* Move genaccounts code to be reused

* Switches nonce increase to always happen in ante handler

* change SetNonce from keeper to point to actual nonce operation

* Remove no op nonce switch (not needed with clearing cache)

* Changes to update all accounts pre state transition and clear cache at end of block

* Update accounts before end of block commit (edge case where necessary)

* Fix nonce of sender going into evm in case it's checked, and let evm set contract starting nonce
