custom_commands + fallback for the older configurations

[Dzordzu]

1. Added custom_commands
2. Implemented custom_search
3. Implemented custom_serach_interactive
4. Added fallback for the command in the keymaps

Synchronized with the upstream version of the #339. Adds a fallback for the older keymap command parameter. It is translated into commands with single value. command takes precedence over commands

Also see #338 for reference

@kamiyaa I've done some sync. Let me know you've got any issues/suggestions to apply :)

[Dzordzu]

@kamiyaa Just want to ping you. Before the codebase changes again ;)

no custom commands need.
all shell command was custom commands.
the only thing need to concern was pipe_out and pipe_in

• pipe_out was done by %s
• pipe_in joshuto need to deel has only two:

1. dir to cd.
2. file/files to select.

maybe only need to read it from standerd output.

Not exactly. The purpose of the custom_commands is to provide some simple flexibility inside joshuto built-in commands. It's a quick patch, that does not require massive code changes and refactoring.

Honestly, I do not understand rest of your message.

about fall back to old command, maybe there's a third way: use just old command, and add a separator such as && or ; to support multi command.

then, the define of custom command was the first thing.
i guess the custom_command means custom search or sth like that.
if there is a way to make more flexiability of inner commands, that's very good.

i mean the search_fzf z zi or such an thing, may be able to be more flexable.
now there's fd replaced find, image years later, sth comes out to replace z fzf, our joshuto still support it without any coding update?
or now, i wonder rg to be support in joshuto?
or now, i have an custom script to search out my files. how could i integrate it to joshuto ?

all these things can be done just with a litte restructure :
just receive piped back result after executed shell command. that's all.

for example: rg/fzf/z, they just do their own job.
joshuto should not hard code them, but trait them as a common shell command.
and receive the result after execute.

• if the result piped back is a folder, just cd to the path in joshuto.
• if the result is a file, just select it. (if not current dir, cd to the path).
• if the result is many file/folder, just display them in one place. (just as search or flat command does)

this will be more flexable to all custom needs.

in ranger, shell -w wait user to have a glance to the command result.
maybe we could:
shell -p to pipe the result back to joshuto.
shell to run the command background and do nothing.
shell -r to run the command background and reload current dir in joshuto .

LGTM! Thanks!
