Restore bug with --no-privileges

Hello,

There's a spelling error on line 319 of frm/frmRestore.cpp in the
current 1.12.1 release of pgAdmin that prevents restores from
functioning if the "Privileges" option of the "Restore Options #1" tab
is checked.

To correct this, line 319 should be changed from:

cmd.Append(wxT(" --no-priviledges"));

to:

cmd.Append(wxT("--no-privileges"));


Thanks,
-Conrad
