[Openstreetmap] new static renderer, and other bits

[SteveC]

I've hacked together a new static renderer in ruby to replace the old
one, which was written in Java.

The 'scale' attribute is now the number of degrees per pixel, and should
be accurate. Scale in the old one was 'roughly the number of pixels per
meter on a Sun monitor from 1994'. I kid you not:

There is also a bar at the bottom right to show you how long a kilometer
or 10 or 0.1 is and so on. There are many cosmetic things to be done,
like drawing black lines with thinner white ones on top instead of just
black lines. And changing the thickness of line with scale...

The 'edit this map' link now goes to a default scale on the applet. When
the high-vitamin goodness of Tom's applet comes online the static
renderer and applet will again show the same thing.

I've changed the image size slightly, what do people think?

As part of this, I've started a DAO to talk to the database from which
a new api handler will be written in ruby. We should also be able to do
RESTful things.

Also today, last weeks ecourier data was imported. Another 300,000 odd
points.

have fun,
