feedster now open for pinging

feedster now has a ping interface. no changes.xml or any other way for others to get the ping data, naturally. i almost feel guilty for the whole feedmesh thing not getting any traction. but blo.gs is currently hobbled by a bug in mysql, and i have next to no energy or enthusiasm for dealing with computers outside of work. which isn’t to say that it is much greater inside of work. i did finally make blo.gs self-regulating to the point that when the server crashes and has to rebuild, it doesn’t just grind to a halt.
