aspellWithDicts: create derivation with aspell and selected dictionaries
Currently, `aspell` checks the active profiles for dictionaries. While this may be convenient, it does not work with `nix-shell` and it doesn't allow any isolation. This commit adds the possibility to use composition by creating a derivation with `symlinkJoin` that contains all the chosen dictionaries, and another derivation that wraps the executables linking to the dictionaries. Nix example: my_aspell = aspellWithDicts(ps: with ps; [ en nl ]) `nix-shell` example: nix-shell -p 'aspellWithDicts(ps: with ps; [ en nl ])'
