[Tilecache] Tile naming

[Roeland Douma]

However when converting lat to -lat the problem seems to be solved.

I think it is a small bug in tilecache since the request goes like this

tilecache.cgi/1.0.0/osm/10/525/336.png

zoom: 10 
lat: 52.482780222078212,
lon: 4.5703125

While the filename (with Disk.py) is
10/000/000/525/000/000/687.png

which means (if i'm correct):
zoom: 10
lat: -52.482780222078212,
lon: 4.5703125

So I have a work around. But I would like to know If I make a calculation 
mistake or tilecache.
