[Tilesathome] Proposal: Keeping tileset as one file

mod_tile ( http://trac.openstreetmap.org/browser/applications/utils/mod_tile
) is doing much more than it's neccessary for t at h tiles serving so I
don't think it's a good idea to use it as-is to server t at h tiles. But
it might be good starting point.

I'm not really sure about mapnik's metatiles. Uploading will get
slower, metafiles will be a bit bigger and format is not suitable for
saving metadata.

On the other hand having tiles for one zoom in metafile is better for
serving and utilities are already written.
