Add nbak plugin to backup all nnn config (#528)
* Add nbak plugin to backup all nnn config
* nbak: check cd, quote env
* nbak: print backup file name
* nbak: add --show option, to show shell config
* nbak: fix shellcheck warning
'type' is POSIX complient, AND we check that we're actually running
bash, but shellcheck can't understand this...
Then '-o' is POSIX complient too, but shellcheck thinks it's "not well defined".
* nbak: variable renames, archive hierarchy changes
* nbak: fix variable expansion
* nbak: remove --show option
* nbak: call interactive bash/zsh to get fun/aliases
* Add nbak entry in plugins/README.md
* nbak: change archive hierarchy
* plugins/README.md: make nbak description shorter
