Rebranding to Kentico Kontent

[petrsvihlik]

Hi @JanLenoch !
We've just renamed Kentico Cloud to Kentico Kontent. We are in the process of renaming all SDKs, developer tools, and sample apps. Please consider renaming your plugin (code: namespaces, classes; repo, wiki, GH topics, etc.) to Kentico Kontent. See the guidelines at https://gitter.im/Kentico/Kontent?at=5d8b643d692d464f7969c6d9.

Thanks!
