- Move lgi to luaPackages
- Use luaPackages in awesome and passthru lua
- Allow to pass lua modules to the awesome WM so that those can be used in the configuration
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
