Log Message:
Fix more peak.web problems:

* Errors were trying to create a substitute context for themselves by
  walking to the parent context and then back down.  This didn't work
  properly for an error that occurred at the application root.  So, I
  added an 'ITraversalContext.substituteContext()' method that provides
  the necessary support, and removed the hacky code from WebException.

* Some code in peak.web.resources was still using an older error interface.

The first problem was uncovered by Radek Kanovsky, and I found the second
while trying to figure out what caused the first.
