• doc/configuration.html: change g_ldap_organisation to g_ldap_organization
• config_defaults_inc.php
  (g_ldap_bind_dn): add config variable
  (g_ldap_bind_passwd): add config variable
  (g_ldap_organisation): removed in favour of g_ldap_organization
  (g_ldap_organization): replacing g_ldap_organisation for consistency
  (g_ldap_port): add config variable
• core/ldap_api.php: change g_ldap_organisation to g_ldap_organization
• core/obsolete.php: add an entry to notify that g_ldap_organisation is obsolete and g_ldap_organization is now used

I hope this is right. I originally was fixing the problem that Robert's new config options weren't initialized in the default config file. Then I noticed the two typos in the README. Then I noticed that our config option spelled organisation with an 's' but the LDAP field name (and most of the example of organizationName I could find relating to LDAP on Google spelled it with a 'z'.

If anyone objects, I can revert this. I wouldn't normally rename a variable name because of an alternate spelling but this seems to be a case where we're not using what everyone else uses in this context.
