issue forms

Proposal

GitHub has recently gained the ability, to not only use "Issue templates", but to create "Issue forms".

When using such an Issue form, the user is guided through the process of providing the necessary information.

See the GitHub documentation on Creating Issue Forms

I really like this, as the simple markdown templates we currently have, are often ignored by the users. (Form templates allow for required fields; and for dropdowns,...)

Also, while the markdown templates (that we currently have) can be rendered a formatted (HTML-)view, the default view one gets when filing a new issue is just the plain text, making it often a bit hard to navigate.
