[Suggestion] Add urls in package.json for easier updating

[shinenami]

This will allow to properly add it as a community repository in VCC, it will then be easy to see when theres a new version of emulator and update it for all projects with one click

Right now we are looking into adding this repository as a curated package. Only if this isn't possible, will we look into making it a community repository. Wouldn't want two versions of the repository floating around.

You can track the progress for this at:

Closing this as we are now Curated :D
