Now it generates notifications for auto-detected devices as well as
for explicitly configured ones, sends well formed e-mails and supports
immediate `wall` and `xmessage` notifications.
`cups.desktop` that depends on some fixed version of `xdg-open` is not
particularly useful; it should use `xdg-open` from the environment
it's being run from.
As a side effect, one can now fiddle with `xdg_utils` package without
rebuilding pretty much every single one of graphical packages (they
all depend on `cups` through their graphical toolkits).
It was broken by cmake updates (between 3.2.2 and 3.3.1).
I chose the github tarballs because they have a predictable URL,
although they're much larger due to not supporting xz.

Unbreaks some packages because they require py>=1.4.29. Example build
error, from the 'argh' package:
The 'py>=1.4.29' distribution was not found and is required by pytest
`nox-review wip` shows that there is a net reduction in build errors with
this patch.
Avoids this warning when running `nixos-rebuild switch`:

Currently the lightdm test detects a successful login by OCR'ing the
screen and searching for the clock widget's text. Since the last
IceWM update (commit bdd20ced), either the font or the colors of the
clock changed such that the OCR doesn't pick it up anymore.
Instead, just look for a matching (root) window title, e.g.
"IceWM 1.3.9 (Linux/i686)"
This improves error messages when a set or a list is used where a path
was expected. For an example, if you used a package set (as opposed to a
single package) in systemPackages before this commit, the error was:
```
cannot coerce a list to a string, at "/home/nixpkgs/lib/types.nix":103:37
```
Now, the error message reads:
```
The option value `environment.systemPackages' in `/etc/nixos/configuration.nix' is not a list of paths.
```
