[DISC]: Handling ctrl+c input in resencmd

[asreimer]

What do we do with ctrl+c encountered in the resen shell? Ignore it? Exit? If a command is running, stop the currently running command?

We need to discuss this. Sparked by #25

Here's one possible solution, but this doesn't help us clean things up if things are partway done when a ctrl+c is encountered.

We need to be careful about how we implement this depending on the OS we are running on: https://stackoverflow.com/a/52941752

My preference would be that a keyboard interrupt event will stop the command that is running. If in the shell go to a new command prompt (or ignore it). And if you are in the middle of writing a command: don't execute it and go to a new empty command prompt.

Summary from today's meeting:

1. initally implement a catch for ctrl+c so it doesn't kill resencmd.
2. investigate how to catch ctrl+c and cleanly handle it for different commands in resen
