A new optional section of the configuration defined using the lua return
statement, which can be used to define append only things, such as hooks
and callbacks, specific to each config file.
Example
```lua
version = "0.0.0"
return {
-- Adds messages to pass when xplr loads (similar to `--on-load`)
on_load = {
{ LogInfo = "Hello xplr user," },
{ LogSuccess = "Configuration successfully loaded!" },
}
}
```
- BREAKING: Rename mode `create directory` and `create file` to
`create_directory` and `create_file`.
- Add key binding `gp` to go to a given path from input.
- Add function `fn.builtin.try_complete_path` to auto complete the path
in input buffer.
- Use `tab` to auto complete path in `rename`, `create_file`,
`create_directory` and `go_to_path` modes.
- Show different prompts in different modes.
And some cleanup.
