This removes the need for monolithic unit definitions and allows
users to modify existing units.
Example:
```
{
systemd.user.services.owncloud-client.Unit.OnFailure = "my-notify-service";
}
```
Unfortunately this duplicates some code from NixOS but it does allow
much more flexibility and, hopefully, stability in the Home Manager
documentation.
Fixes#254.
This is needed to support overriding these options inside match
blocks. A new option `programs.ssh.extraOptionOverrides` has been
added to allow global overrides.
This option enables a GPG Agent restricted socket (aka "extra-socket"), which
can be used to forward GPG Agent over SSH.
Additionally `verbose` option enables verbose output of an `gpg-agent.service`
unit for easier debugging.

It is safest to use the system install of Nix since that will be
compatible with the running nix-daemon and/or databases.
Also add a printout of the used Nix version in the activation script
when running in verbose mode.
Fixes#218.
Curiously the `who` command sometimes does not list logged-in users,
resulting in systemd not being reloaded. Instead we use
systemctl --user is-system-running
to more directly detect whether systemd is running.
The preferred method of theming rofi is now to use "rasi" theme files.
This commit therefore downplays the colors option and introduces the
theme option.
This is a NixOS module that is intended to be imported into a NixOS
system configuration. It allows the system users to be set up directly
from the system configuration.
The actual profile switch is performed by a oneshot systemd unit per
configured user that acts much like the regular `home-manager switch`
command.
With this implementation, the NixOS module does not work properly with
the `nixos-rebuild build-vm` command. This can be solved by using the
`users.users.<name?>.packages` option to install packages but this
does not work flawlessly with certain Nixpkgs packages. In particular,
for programs using the Qt libraries.
