[FEAT] Adding custom dirs via environment variables

[JohnnyCena123]

Description

what I propose is to be able to use environment variable, say FF_CONFIG_DIRS, as a colon-separated list of directories in which fastfetch would look for config files. ideally, they would precede in priority to the default ones.

Motivation

I found myself using multiple different fastfetch config files, and I would like to have the option to add custom search paths for them. currently fastfetch hardcodes to only search for config files provided via -c or --config in the platform data dirs. this is not ideal for adding custom search paths.

Additional context

currently I do not have any code to provide, I would first like to know if this is a thing that would be merged.
thank you in advance.
additionally, it could be useful to some extent if fastfetch searched recursively for config files provided via the command-line in each search path.

I don't think it's a good idea, at least not an intuitive way.

Instead, fastfetch -c now searches paths listed in fastfetch --list-config-paths, so you just put all your configs inside ~/.config/fastfetch

Not sure why fastfetch didn't do that at the first day though.

[JohnnyCena123]

fair enough. thanks anyway

it might as well fit to update the *sh completion for fastfetch
