Printing VM log messages to the console

Logging of VM messages is not enabled by default.

It can be enabled from the image using GtVirtualMachineConsoleLogger Object subclass: #GtVirtualMachineConsoleLogger instanceVariableNames: '' classVariableNames: '' package: 'GToolkit-VirtualMachine-Logger' .

Log all default types of messages

GtVirtualMachineConsoleLogger startFor: GtVirtualMachineLevelSignal
  

Log specific types of messages

GtVirtualMachineConsoleLogger startFor: GtVirtualMachineTraceSignal, GtVirtualMachineDebugSignal
  

When there is no more need to have log messages printed to console we can stop the logger.

GtVirtualMachineConsoleLogger stop.
