Add "copy version information" to About dialog

[tigert]

Is your feature request related to a problem? Please describe.
You are required to enter version information from MobiFlight when you are reporting a bug. It would be useful to have a button in the About dialog that copies the relevant information as a text snippet on the clipboard, so that you could paste it on an issue report.

Describe the solution you'd like
something like what KiCad and FreeCAD both have:

The nice thing is once this workflow is in place, and people are expected to use it, we can add things like current aircraft, the simulator in use, available devices, etc in the information snippet.

A bit like the "copy logs" feature, but for general system and version info.

I like the idea... even more advanced: "Report bug" in menu where it takes you to github and it might be possible to fill in some information automatically. That could also show whenever a exception occurs which is not handled.

Let me check if github allows for providing certain information as URL param. But it could also be a custom website... yeah! It would require a user login. That would be cool
