Move Error functions to a Controller

[eluser]dakta[/eluser]
Just found this thread (thanks, Google), and would like to thank you for saving me a tremendous amount of hassle.

Just one thing (besides minor renaming for CI 2.x compatibility, which I already did): how do you use this to catch PHP errors? I can currently catch 404 errors just fine, but forcing PHP to throw an error causes the default error handler page to be used. I have already created a new condition in the _remap() function, added a relevant handler function (_error_php()), but it doesn't seem to have worked.
