224: Allow for directories in module-list r=nrdxp a=Pacman99

fixes #221 
building on #222 this PR improves the lib functions pathsToImportedAttrs and pathsIn. First to add support for directories. This does not support actually passing a file in a directory, so `./matrix/default.nix` won't work but `./matrix` will - I should probably document this somewhere. 
Also I moved the filtering for nix files to `pathsIn`, since its only necessary for auto-import. We can assume that users would pass proper files in `module-list.nix`.
