Doing `throw <myExceptionVariable>` causes the stack trace information
to be rewritten (we don't want this). Wrapping in a new exception object
like `AggregateException` fixes that but also makes the printed
exception look messier.
Instead, simply return a bool to indicate if `HandleException()`
processed the the exception; if not, then we can rethrow from outside
the method.
Previously, the exception stack trace was omitted to simplify the
console output. However, some situations occurred where an exception was
logged but I couldn't tell where it came from. This made certain rare
bugs impossible to fix.
My philosophy at this point is: If something exceptional happens, we
don't really care about a "clean" console output anymore...
