Is your feature request related to a problem? Please describe.

When creating a bug ticket one is asked for OS version and NAV version. An exception debug page or exception email currently does not contain this information, so it takes longer to file the bug report, or worst case the information about OS and ANV versions are not included in the report.

Describe the solution you'd like

Have the information in the generated debug output. NAV version could be hardcoded in a setting, which would make it available under the "Settings" header. For discovering the OS version a function/method would be needed.

Describe alternatives you've considered

Instead of using debug emails, the exception information could be sent to a service designed to deal with such, like "sentry". The info about NAV version and OS version would still need to be available somehow though, and the support for an external error-handing service would have to be configurable or turned off, so while this is a better solution, it is not a sufficient solution.
