[mkgmap-dev] closed ways and multi-polygon relations

Hi Gerd,

I see 3 possible solutions:
1. Convert multipolygon ways to a proper, continuous outline.
2. Return is_closed() as true, when mkgmap:mp_created is true.
3. Add info to documentation, that lines with mkgmap:mp_created=true are 
part of a closed outline, but not necessary result in is_closed()=true.

I would suggest solution 3.

I assume that is_closed() means, that object could be a polygon, while 
mkgmap:mp_created=true or area=yes describe a more complex object, but 
essentially a kind of polygon too.
