jing-trang: update to version 20091111

Also add meta attributes and a wrapper for jing so that it can be
invoked directly from the shell as "jing" (similar to Debian/Ubuntu).
Trang already has such a wrapper.
duply: platforms.unix -> platforms.linux

Dependency ncftp fails to build on freebsd and darwin.
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
