* Don't serialize Account Number and Sequence Number in signatures
This was not needed to be included within the tx body, as its in the
state.
* fix lint
This PR begins improving the godocs for the auth module, and begins cleaning
up the Ante handler.
Additionally we previously calculated if the fee was sufficient for the tx
on every single signer. This is now refactored to be more efficient, and have
a better logical flow. No changelog entry as this is new to this release.
* Add an example for the size of a transaction
This shows that the size of a send tx from 1 input to 1 output is 173 bytes
This is good information to have, though we need to find the correct place
to put it.
* fix lint
