Release Notes

* Added new DNS plugin for Simple DNS Plus (#149) (Thanks @alphaz18)
* Changed a bunch of "-ErrorAction SilentlyContinue" references to "Ignore" so we're not filling the $Error collection with junk.
* Fix for Boulder removing ID field from new account output.
* Fixed an issue in a number of plugins that could cause errors if the case of the requested record didn't match the server's zone case. (Thanks @Makr91)

* Fixed some typos in the OVH plugin usage guide examples (#147)
