Refactored RequestProcessor swallows all exceptions in BlockServlet case

[Alexander Klimetschek <al...@mindquarry.com>]

Hi Daniel,

while updating to the latest Cocoon I stepped into the problem that you 
cannot see the exceptions thrown in a BlockServlet called by another 
one, since the new refactored RequestProcessor swallows all exceptions. 
The generated error page is fed into the response output stream which is 
eventually read by anything in the calling pipeline, which mostly cannot 
handle that html error page (in my case it gets some xml) and will throw 
another exception like SAXParseException.

IMHO the RequestProcessor should throw the exceptions in the blocks case 
  instead of generating error pages. I am trying to fix that.

Alex
