Merge "develop" to "master" and release new NuGet package version

[davidnguyen]

Hi, I'm trying to get Atlas to work with Sitecore 9 and it's all well and good except the LinkFieldRenderingString class still has some dependency to CommonServiceLocator. In Sitecore 9, CommonServiceLocator is still used, but reserved for Solr integration only. This breaks on any ViewModel class that uses ILinkFieldRenderingString. The fix for this has already merge to the "develop" branch. It would be great if it could be merged to master, and release a new version of NuGet package.

Thanks, David Nguyen
