Catching pre-controller level exceptions

[rx]

egregious is catching exceptions at the controller level, if an exception occurs in the stack before the controller code it is not caught by egregious. This causes low level errors to be returned in standard rails html formatting.

The ability to hook lower level exceptions, using the same mechanism that hoptoad/airbrake uses would resolve this issue.

if anyone want's to take a stab at this create a fork and send a pull request once you're confident it is working.
