Work with sonarr

In attempting to get this to work with sonarr, it appears they do a version check by querying
?action=getsettings

Adding an endpoint for this should get it to work with sonarr. The specific version check in sonarr is here

I've tried the above but can't get it working -- sonarr error: Old uTorrent client with unsupported API, need 3.0 or higher. My guess is that sonarr isn't parsing the build property correctly for some reason
