Place names and power lines

Looks like this has already been taken care of in the mailing list.

A new update is running using the stable Mkgmap r1867 and with power=line added to the pre-filtering.

However, it occurs to me that the boundary levels 8, 9 and 10 are also filtered out but are probably needed for the address search when the mkgmap-locator branch is merged with trunk…?
