[Openstreetmap] [PATCH] Make it easier to change the default map location

[Petter Reinholdtsen]

Here is a patch to make it easier to change the default map
location/scale for the server side map drawing.  It is untested, as I
lack a working test environment.  But I believe it should work.  It
might be better to mark the default values as static values, but I
didn't do this in this draft patch.
