Improve Exception reporting

Need to improve exception reporting.

2 considerations.

1. At the crash dialog, allow copying of crash details, and open directly to here on GitHub to log a crash report. (Unless there is a Url query string to allow automatic pre-fill of a form.)
   See this example: https://github.com/midspace/SEToolbox/issues/new?title=Crash+Report&body=The following+details&labels=bug,question
2. Automatic Exception reporting
   Implementing an automatic method for logging exceptions, a little like how Keen do it with Space Engineers would help considerably in collecting bug reports.

The Unhandled exception dialog should also prompt the user for whatever they were doing at the time of the Exception, and ask for any files/links they think may be important.

I'm guessing a dedicated web page, .PHP hosted somewhere that accepts a specific POST message, which will in turn email it to us.
SEToolbox can post to that specific page, with any and all detail on the error.
Some basic checks on POST fields, and on the Referer and UserAgent to prevent too much abuse or spam.

Start by locating the Unhandled exception dialog and tracing how crash details are currently presented. The issue does not name files or tests; define the scope for copying details, opening a prefilled GitHub report, prompting for context, and any automatic reporting endpoint before implementation.
