localization of client tools

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

I've made a number of commits based upon Masato's
gettext patch (ITS#2410)...

Basically, developers can wrap translatable 
strings as follows:
	char *str = _("translatable string");

Masato has marked strings in the client tools.  These
need to be reviewed.  Client libraries also need marking.
Feel to submit patches here.

Don't yet mark strings in slapd(8).  Special consideration
is needed here as the end-user may be in a different locale
than the user running slapd(8).

Masato also provided some translations.  I haven't
committed these as the strings he's marked need to
reviewed.
