Revert what was done in c5021721 : I then added a panel to be rendered instead of throwing an Exception. This was done because the exception was displayed in a blank page... But this was caused simply by a missing `use Exception` !!
So now we're back at throwing an exception, so that the standard mechanism for throwing the error page is triggered.
Handling Twig recursion is mandatory, and done in the beginning of the \Combodo\iTop\Application\TwigBase\Twig\TwigHelper::RenderTemplate catch block to avoid adding on each stack level a useless exception.
Original files kept for compatibility issues :
- core/coreexception.class.inc.php
There are remaining exceptions in /core/oql, but those files are generated
