Fix #4 Improved exception reporting: Entire exception instead of message only.

[BrunoJuchli]

The ExceptionReporter now prints the full exception, including stack trace, to the console.
This is intended to fix #4

.ToString() is actually quite neat. It will print this for an exception with inner exception:

System.InvalidOperationException: Master says you no good. Inner Exception you shall peek for ennlightement! ---> System.ArgumentException: nada nadie burranga
at Pmr.Fdms.Utilities.temp.ThrowSomeException() in c:\development\fdms\03_Source\DesktopDispatchConsole\Utilities.Tests\temp.cs:line 36
at Pmr.Fdms.Utilities.temp.RethrowThrownExceptionAsInnerException() in c:\development\fdms\03_Source\DesktopDispatchConsole\Utilities.Tests\temp.cs:line 26
--- End of inner exception stack trace ---
at Pmr.Fdms.Utilities.temp.RethrowThrownExceptionAsInnerException() in c:\development\fdms\03_Source\DesktopDispatchConsole\Utilities.Tests\temp.cs:line 32
at Pmr.Fdms.Utilities.temp.FooBar() in c:\development\fdms\03_Source\DesktopDispatchConsole\Utilities.Tests\temp.cs:line 14

I don't think there's a lot of risk that this will change - as there's lots of tools relying on this.
What did you have in mind? Can you point me to a better explicit / proper formatting code?
