Bug 9001: Remove Zebraqueue_daemon

[This patch was split out from tcohen's excellent patches for bug 8519
 --jcamins]

It removes the obsolete zebraqueue_daemon.pl and koha-zebraqueue-ctl.sh
obsolete scripts too.

Several files are modified to address te removal/addition of these files.

I didn't run the install procedure as I was working on my laptop with a dev
setup, just set the symlinks. Now fixed things as proposed by wajasu
on comment #4. Any other suggestion please let me know.

Tested to work on an up-to-date Ubuntu 12.04.

Asked by wajasu, remove remaining obsolete zebraqueue stuff.
