6502bench/SourceGen/WpfGui/MainWindow.xaml.cs
Andy McFadden 02f6e884d7 Fix startup issues 
- MakeDist now copies CommonWPF.dll.
- Spent a bunch of time tracking down a null-pointer deref that only
  happened when you didn't start with a config file.  Fixed.
- The NPE was causing the program to exit without any sort of useful
  diagnostic, so I added an uncaught exception handler that writes
  the crash to a text file in the current directory.
- Added a trace listener definition to App.config that writes log
  messages to a file, but it can't generally be enabled at runtime
  because you can't write files from inside the sandbox.  So it's
  there but commented out.
- Made the initial size of the main window a little wider.
