#3420: Twisted web Resources should "return ErrorPage" instead of  "raise
WebError"

---------------------+---------------------------
 In case of errors, twisted.web `Resource` instances should be responding
 with an error page, instead of throwing an exception.  Any `raise
 WebError` instances we have in Tahoe WUI should be replaced with `return
 ErrorPage`.
