Title: Do not put irrelvant tags (source, created_by, converted_by) in the data...

Please consider pulling this change. It removes tags that are irrelevant for the map creation (currently: "converted_by", "source" and "created_by") from the nodes.tmp database.

result of this change: smaller nodes.tmp.odb database (about 100 MB less for the austria.osm), faster processing (due to less disk I/O).

On my system (Athlon X2 with SATA disk), this patch saves some seconds on the first step of the processing; so the cost of the comparison of the strings with the tags is smaller than the time for writing to disk.
