[OSM-dev] Connection Limit

I have applied a connection limit to the web server on www.openstreetmap.org
that limits the number of simultaneous connections from any one IP address
to twenty. After that requests will get a "403 Forbidden" response.

This was primarily done because a pair of IP addresses were bombarding
the server with map requests to the API and the server seemed to have
more or less ground to a halt as the requests were coming in faster than
the server could handle them - there were in fact over 220 connections
from those two addresses when I applied the limit.

The limit might need some tweaking, so do shout if you see any problems
as a result of it, but for now the server seems to be a lot happier than
it has been for the last few hours.
