Replace hack with output buffering and second error handler

[GoogleCodeExporter]

The error handler has a hack to remove Error Code 8.  This is in general a bad 
thing for controller code, but a good thing for template code.

Create a template error handler.
Switch to the template handler around the template, then back when the template 
is done.
Output buffer the template.  In error handler, clear the output buffer and die.
