>Moving towards better i18n support in SWAT.  This commit contains a
>bunch of updates to bug 413 from Monyo:
>
>1) pick up proper strings to call msg strings for example to add
>  strings in wizard menu in web/swat.c, web/statuspage.c and
>  param/loadparm.c.
>
>2) define N_() macro in include/intl.h to pick up some strings
>  in param/loadparm.c
>
>3) quote all name and value tag with '"'
>  For example in swat.c:720 the "Edit Parameter Values" string is
>  displayd only as "Edit" because value tag is not quoted like:
>  value=Edit Parameter Values
>  These tags should be quoted though it sometimes works well
>  without quotation.
>
>4) modify the msg strings not to contain HTML tags or other
>  non-message strings. For example
>  dprintf(_("test\n")); is modified to dprintf("%s\n", _("test"));
