New output_history.clifm

[theRoboxx]

I had another idea as a result of this feature #292:

A output_history.clifm file to log the last X commands with the corresponding output.
Like history.clifm but with the output of the command.
The use case would be for resource intensive commands that you don't want to execute again but need the output.

The default value should be off.

Not sure about this one. But I'll see what I can do.
