CTRL-C will now exit the program

[Luk164]

Just a simple piece of code added to the end of the file + two booleans to check if files are being written to. Also does not allow files to be written while shutting down and will automatically reject incoming connections. Relates to issue #13

I tested this PR but it isn't working for me. If don't save any changes it shutdows with Ctrl-C. But after I have saved any change in the scene Ctrl-C no longer works

Update: Seems to be a problem with the package prompt-confirm capturing the input and not reporting the SIGINT signal. See enquirer/prompt-confirm#9

@Juankz That repo seems to be dead, I dont really know how to proceed here

[Juankz]

I talked on discord with one of the maintainers, the repo is not dead but is not much active either. If you could help testing my PR it would make it easier to merge.
