[OSM-dev] tiles cut corners

Still the old data makes it currently necessary to do several nested
subselects within one statement.

So even onle one old data entry hurt the select statement by a factor that
not depend on the number of old entries but on the number of CURRENT
entries.

We could save the tags in different tables, seperated from the other data
objects.


Ciao, Imi.
