Mirror the linting of the upstream sdk

[evan-forbes]

There were two nolint directives added in #19 that mute the linter. These should be removed, or kept, depending on what the upstream cosmos-sdk does about some utility functions that were removed in the tendermint master branch, but kept in the latest release

We have a few options, one of which should eventually become the clear solution, as this linting issue is a tad complex. It's unclear if the linter should or shouldn't be picking up the write permission error. There are many different permissions used, including a few 0777. They seem to be avoiding detection, as the linter misses fucntions that use the tmos package. Ultimately, we should probably do whatever the cosmos-sdk does. For now though, the nolint directive has been added for our own sanity.
