* Added new tests
* Added the port to reload's return object so the calling program knows what port reload ending up using if the port auto increments
* Added autoIncrementPort optional param to realod to turn off auto port incrementing. Default `true`
* Tweaked the code to work correctly, like handling the promise return correctly
* Small tweaks to how the generated client side code replace works. Removed a branch that wasn't hitting in coverage and made it more readable
* Updated README with API changes
