[Tile-serving] [osm2pgsql] Fix style.lua error with non numerical layer values (#145)

[Tim Waters]

The value for the layer tag should be numeric. But there are a few non numeric values in the OSM db - http://taginfo.openstreetmap.org/keys/layer#values This causes an error of something like: "attempt to perform arithmetic on local 'layer' (a string value)". Thus we check to see if the value is a number.

Full props to @systemed for this!
