[Dave Winer]

A new mechanism to cause River4 to quit, used in the ec2ForPoets updating mechanism.

Note -- I changed the implementation of River4's change detection, made it much simpler.

If the feature is enabled (it's disabled by default) we check the mod date of river4.js every second to see if it's changed.

If it has we do a process,exit (0) -- which presumably will cause the app to be re-launched, thus running the new version.

The previous version was way too complicated, this works better and is much simpler.

Does this remove the need for forever?

When River4 quits, something has to launch it. 

So we're actually *depending* on forever, or something like it, to be watching over River4, and relaunching it when it quits.
