As an administrator I want to be able to automatically create a backlog item from a bug report

[IzKuipers]

This issue reintroduces brissue: a system I wrote for the old ArcOS-Reports-Panel that allowed us to automatically create a GitHub issue from any bug report. This will come in handy when distributing the bug reports between devs, making that whole process a lot quicker and more consistent. This comes in two parts:

• The backend part: built into ReArc, this will serve as the proxy between ArcOS' bug report system and the GitHub organization, with admin scopes
• The frontend part: a GUI implementation wired into the admin portal that allows permitted admins to create issues for bug reports
