ue4jam tab in Epic Games Launcher and publish option in Unreal Editor

The launcher should have a tab where all the submissions for each #ue4jam are available to submit, download, review (stars / vote) and comment.

It would make it ridiculously easier for everyone if the Unreal Editor had the option to publish straight to the Epic Games Store.

This could effectively form the foundation for Epic to have their own “greenlit” system like Valve.
