[HOT] [Ebola] Import of 14, 020 United Nations Mission in Liberia place nodes

A few more observations, probably not new to fellow importers,

   - often when it seems UNMIL objects are placed in the mid of the jungle,
   there is an isolated dwelling somewhere
   - often when I encounter very different GNS vs. UNMIL place names in a
   hamlet area it's worthwhile to look far outside (1km) for a UNMIL node that
   matches the GNS node better. Voila, misplaced GNS node found.
   - for the same reason I always do a final scan of the square, looking
   for offroad GNS nodes that might match a lone UNMIL node. Usually I find
   one or two.
   - this is more controversial. We are told to keep A, B, C or #1, #2 in
   place names. I don't question that in general. However when I find big
   villages that have a GNS name (say Bopolu) in the center, and five UNMIL
   names (say Bopolu A to E) very near to that, then I think it improbable
   that Bopolu has five suburbs named so, because else the UNMIL objects would
   be distributed much more evenly over the area. I have condensed it all into
   one object (with 5 UNMIL ids so the are not lost) in such cases. I have had
   less then five such cases so far, no worry. But it makes me speculate that
   most names with additional A, B, C are automatically generated, because I
   find that the larger the hamlet/village is the more such objects are found.
