Bug 17030: Enable REST api on packages

This patch enables access to the REST API endpoint on packages setup.
It does so, by patching the shared apache-shared-intranet.conf and
apache-shared-opac.conf.

You can build your own master packages with this patch applied, or just:

- Grab
  debian/templates/apache-shared-intranet.conf
  debian/templates/apache-shared-opac.conf
and overwrite their counterparts in /etc/koha on a packages setup. For example
in kohadevbox.
- Have Koha loaded with all default data
- Create a superlibrarian user for you
- Login to the intranet and the OPAC
- Point your browser to:
  http://localhost:8080/api/v1/patrons/51
=> SUCCESS: You get JSON data, for the patron you requested
  http://localhost:8081/api/v1/patrons/51
=> SUCCESS: You get JSON data, for the patron you requested
- Sign off :-D

Note: I use the HTTPRequester addon for Firefox, re-using the CGISESSID value from the
browser session cookie, in the headers.
