Using east_west_north_south_box doesn't work at all

[barny]

AFAICT the geonames_rdf library doesn't convert the east_west_north_south_box bounding box parameter into HTTP/REST parameters correctly - it applies a single parameter "east,west,south,north" when the four values should all be individual parameters.

To fix this, in geonames\adapters\base.py, change:

def east_west_north_south_box(self, value):
    return self.set_string_parameter('east,west,north,south', value)

to this, which seems to work for my simple testing:

def east_west_north_south_box(self, value):
    for coord,val in zip(['east','west','north','south'],value):
        self.set_string_parameter(coord, val)
    return self
