Allow opening the Bugtracker from Unhandled exception Window

[JakobDev]

Is your feature request related to a problem? Please describe.
When a Python script in windowed mode has a unhandled exception, a Window with that exception will open.

This is a great feature to show this Windows instead of silencing crashing. But there's one problem: The User don't maybe don't know how to report the crash.

Describe the solution you'd like
Add a new argument to PyInstaller e.g. windowed-traceback-bug-url. If this is set, a new Button called Report Bug will appear on the left side of the Window. If the User clicks this, the Browser will open the given URL, so the User can report the crash in the Bugtracker.

Describe alternatives you've considered

That unhandled exception window is more just a placeholder for your own exception handling. For a production application, we'd rather that you do it yourself. Something along the lines of:

try:
    # your main code here
except:
    import traceback
    error = traceback.format_exc()
    # Display this error message in a popup dialog with whatever formatting,
    # hyperlinks or additional suggestions you like

There might be a case where you can't do that e.g. problems with importing the GUI Framework, so allow adding a Link to the exception Window would be much better.
