We've moved some of the LDAP auth plugin "knowledge" of different LDAP
servers to a common library, and we've added support for nested groups
enrolments for selected LDAP servers.

Lots of changes in the language pack, as all the plugin messages have been
internationali[sz]ed (it also includes renaming of quite a few string
identifiers).

During plugin settings migration, we rename 'version' setting to
'ldap_version', as we store the plugin version itself as a setting in the
plugin config table and the two collided.

Performance is not great for larga data sets but this can be improved later
(20000 users, 4000 courses and 100 users/course take around 1h25m on a somewhat
tuned postgresql-8.4 on a 2.66GHz Core2 Duo w/ 4 GB of RAM).
