Right now PHP simply dumps something like this on the page:
Fatal error: Cannot redeclare Cms\getItemHierarchy() (previously declared in /home/cartman/Development/cmsdev/engine_1.0/Cms/Menu.php:62) in /home/cartman/Development/cmsdev/engine_1.0/Cms/Menu.php on line 62 Call Stack: 0,0001 634424 1. {main}() /home/cartman/Development/cmsdev/public_normal/index.php:0 0,0037 757768 2.

Is there a way to make the output look more organized, at least print stack trace on separate lines?
This seems to be an XDebug stack trace. Try setting trace_format in php.ini:
xdebug.trace_format = 2 # HTML formatting
