Merge remote-tracking branch 'origin/HEAD' into 7.1.0-ImageCropper-JeavonWIP
GetCropUrl - needed to get the url from within the json within the check for a crop otherwise a exception can occur
Backup config files properly
Fix merge conflict
Also copy the new config files over
If cropper property editor not in use on umbracoFile then we can use mediaItem.Url
No need to back up the config files, they don't get overwritten if you answer "No"

Updated the readme.
