home-environment: include home path in generation directory
Technically not necessary but it was a bit silly to leave out this
important directory from the generation directory. This also makes it
more convenient to browse the installed packages after a
`home-manager build`.

home-environment: use relative latest profile link
Using a relative path prevents the latest version from being garbage
collected.

home-environment: fix error when deleting empty directories
With --ignore-fail-on-non-empty, non-emptiness is the only failure
that gets ignored by rmdir. In the case that rmdir reaches $HOME and
considers deleting it, it will detect insufficient permissions and
subsequently exit with an error, even if $HOME is not empty.

Prevent this by calling rmdir with a relative path that excludes
$HOME.

home-environment: fix cleanup of user replaced directories
We must only follow the symbolic link once (i.e., not use the `-e`
option) since otherwise the pattern will not match when
`home.file.xyz.source` is a directory.

home-environment: fix home.activation.checkLinkTargets
Problem
-------

We resolve symlinks from inside `/nix/store/HASH-home-manager-files`
into the nix store as `/nix/store/HASH-DRVNAME` which does not match
the pattern.

This happened to me because I pull in some repos in via `home.file`.
The `home-manager-files` derivation links to the repo's derivation in
the nix store. For example:

    let nanorcs = fetchFromGitHub {
      owner = "scopatz";
      repo = "nanorc";
      …
    }; in [
      {
        target = ".nano";
        source = nanorcs;
      }
      {
        target = ".nanorc";
        source = "${nanorcs}/nanorc";
      }
    ]

Solution
--------

Call `readlink` without `-e` to obtain only the first redirection from
`~` to `/nix/store/HASH-home-manager-files`.

home-environment: prevent delete of non-managed files
When a file has disappeared between the previous and the next
generations then its symlink in `$HOME` is typically deleted. With
this commit we refuse to delete the path unless we are reasonably
certain it is a symlink into a Home Manager generation.

home-environment: use explicit PATH in activation
In the activation script we expect to use the tools provided by GNU
Core Utilities and GNU Bash. This commit therefore explicitly add
these first in the `PATH` environment variable.

home-environment: prevent overwriting existing files
This should reduce the risk of overwriting an existing file in the
user's home directory. A file will only be replaced if it is a link
pointing to a home-manager tree inside the Nix store.

If an existing file is detected an error is written indicating the
file's path and the activation will terminate before any mutation
occurs.

Fixes #6

home-environment: always link new and clean old generation
Previously the home files were not linked if the generation hadn't
changed. Unfortunately, this would mean that, if a file link was
removed for some reason it would not be recreated by running a switch
command.

home-environment: check files for '.' prefix
Nix does not allow files whose name start with a '.' in the Nix store.
This commit makes a not of this fact in the `home.file.source` option
and also adds an assertion verifying that no such file is given.

Closes #4

home-environment: handle no home files
If no files should be installed into the home directory then an error
would occur since the directory holding the files would never be
created. With this change the directory is unconditionally created.
