Handle platform entries from updates.json. This PR adds capability to identify OS specific releases and offer update notification accordingly. In new update entry format, builds available for specific platforms is being listed under that platform key. If an entry doesn't contains the current platform, we assume the build is not applicable to the current platform.

This is how the new Update entries look like -
