Improve the logging

[arsdever]

The logging of the base should be improved in the way that it better uses the flexibility of the logger, so it uses the log levels in a more accurate way. As for now, lcd_controller traces every time it has an incoming signal and some high level debugging is missing in order to filter out necessary and unnecessary information.

Further refine this task and add subtasks as needed:

• Change the level of the logs on lcd_controller about the instruction being executed to be trace. #31
• Improve the lcd_controller to print more informative logs at level debug or info about the commands being executed. #32
• Log output in GUI #48
• Some log timings are relative to the simulation time #52
