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.

Add basic directed acyclic graph data structure
Also make use of this instead of Nixpkgs's strings-with-deps library
in activation script generation.

Use stricter Bash settings in activation script
For example, with these settings Bash will complain if uninitialized
variables are used. Some code has been improved to run cleanly with
these settings.

home-environment: show full file path in error
The file name alone may be misleading.

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: add link for current profile
This link is needed to make the `delete-older-than` option for
`nix-collect-garbage` work as expected.

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.

home-environment: use Bash to set variables
Until a few more standard variables are available to PAM it is a bit
risky to default to it.

Also make it possible to set session variables using PAM rather than
Bash.

activation sections.

Support dry run in activation script
If the `DRY_RUN` variable is set then no actual change should be
performed. Only printing what actions would be taken.

Use a generation directory
Before we put only user files in the generation directory but that was
quite limiting. In particular, we lost track of the activation script.
