quitcd: fix old bug and feat. for modular export for nushell

[BeyondMagic]

• now users can import as a module instead of just copying and paste with use nnn.nu
• also refactor everything with internal commands, and add commentary, and remove unnecessary --force in rm.
• remove having to import nnn environment variable NNN_TMPFILE, now it only launches for the command.

instead of just copying and paste

There was no need for copy paste. You can just source the file (I'm assuming nu shell has source).

Nushell aims to focus on modularity, by replacing source alike-files with modules we can hide and use whenever we want.

with modules we can hide and use whenever we want.

Not sure if this makes sense or not since this isn't some "library" meant to be used wherever. But then again, I don't use nushell, so I could be wrong.

@J-Kappes @mmai could you guys review and/or test this pull request?

You can start by reading about modules here.

And you can test by downloading nushell and then opening the terminal, typing out the following commands step by step:

1. nu
2. use <this repo>/misc/quitcd/quitcd.nu
3. n

Then go to another directory and exit. There we go.

Think of this by also enabling users to build upon this simple function.

@N-R-K is this good to go?

Waiting for other nushell users to test/review.

Sorry, not interested in downloading/running pre-built binaries and also not interested in compiling thousands of dependencies just to test something I have no intention to use.

@BeyondMagic please squash to a single commit.

@mmai can you please review?

[BeyondMagic]

@jarun done.

Hello @BeyondMagic . Thank you for the modular export. I saw two problems with the config_home setting and the temp file removal.

This looks better. One small nit on the wording of --selective flag.

Fixed, had a few problems pulling from the main branch, but now the log history is fine.
