Bug 8507: koha-create now supports using DOM indexing for bibs

This patch makes the koha-create script install the file zebra-biblios-dom.cfg
with the proper string substitutions inside on the new instance koha-conf.xml file.

It also adds two option switches that control the indexing mode for the instance:

 --biblio-idx {dom|grs1}
 --auth-idx {dom|grs1}

DOM indexing is set as the default for both authorities and bibliographic records.

Following drojf (thanks!) advice I arranged stuff like explained here:

  http://wiki.koha-community.org/wiki/Switching_to_dom_indexing

To test:
- Apply the patch
- Build your own packages and install them on a test server
a) Create a new instance without using the new switches like:
 $ koha-create --create-db domtest
 - Check there's a file /etc/koha/sites/domtest/zebra-biblios-dom.cfg
 - Check that /etc/koha/sites/domtest/koha-conf.xml points to:
   * zebra-biblios-dom.cfg (biblioserver section)
   * zebra-biblios-dom.cfg (publicserver section)
   * zebra-authorities-dom.cfg (authorityserver section)
 - Success means the new default is DOM
b) Play with the 4 possible combination of option switches
 $ koha-create --create-db --auth-idx grs1 --biblio-idx grs1 domtest
 $ koha-create --create-db --auth-idx grs1 --biblio-idx dom domtest
 $ koha-create --create-db --auth-idx dom --biblio-idx grs1 domtest
 $ koha-create --create-db --auth-idx dom --biblio-idx dom domtest
 - Check the koha-conf.xml file reflects the chosen options.
c) Run
 $ koha-create --help
 - It should advertise this addition accordingly.
d) Run
 $ man koha-create
 - Man page for koha-create should provide good information on the new switches behaviour
