Hopefully a fixed version of Refactor: introduce isType reducing redundancy.
Coding-by-sed wasn't a good idea :(
Remove jing_tools expression (now contained in jing expression itself)

The jing expression now creates its own "jing" wrapper script, so there
is no need for jing_tools anymore.

jing hasn't been updated in years, so I assume (or hope) that not many
(if any) have jing_tools in their configuration.nix. If you do, just
change it to jing and it should behave the same.
Trivial change of wording of error messages

Add emacs24-nox: emacs built without X (or GTK) libraries.

This commit also fixes an issue where pkgconfig was only added as a
dependency when gtk support was enabled. This made ./configure unable
to find other libraries (libtiff, libxml2, gnutls, and others).
Don't prefer 'emacs24-nox' over the normal 'emacs24' attribute.
