Use different issue templates (#3695)

This PR will introduce different issue templates for bug reports,
feature requests and so on on GitHub. There is still room for
fine-tuning, but it's reached a state to show it to you and get
feedback.

I think that this can lead to better bug reports.

You can see the result in my repo:
https://github.com/KristjanESPERANTO/MagicMirror/issues/new/choose

Feel free to create new issues for testing.

What do you think? Do we want to pursue this further?
