[Request] Make packages directory configurable

[mfutselaar]

I'd like to leave my packages outside of my Laravel project, please allow us to store the packages outside of the project folder by configuring a different path in the config just like the skeleton location and use symlinks in the composer repositories.

Hi, @mfutselaar
I don't use laravel in my work anymore and I don't have time to implement your feature request.
But prs are welcome!

I think making it global is the best way.
