* Integration tests now have their own list of allowed shebangs.
* Use `#!/usr/bin/env bash` instead of `#!/bin/bash`
since the location is different on various platforms.
* Add tests for WANT_JSON and old style modules
* quote source path
* Attempt to further appease tests
* Check for file and not just exists
* omg don't be dumb
* moar fixes
* shellcheck is the worst :)
* Test the custom modules for failure without arg files
* tolerate windows line endings when loading windows module utils. Helpful for old custom windows modules.
* add test modules to demonstrate win line ending module load behaviour.
* attempt to fix sanity check failures
* pep8 fix
* explict skip of test modules from shebang check (core modules must still have expected unix style line endings)
* switch to rstrip() following core team meeting feedback
