* allow defects to be caught even for --exceptions:goto (WIP) * implemented the new --panics:on|off switch; refs https://github.com/nim-lang/RFCs/issues/180 * new implementation for integer overflow checking * produce a warning if a user-defined exception type inherits from Exception directly * applied Timothee's suggestions; improved the documentation and replace the term 'checked runtime check' by 'panic' * fixes #13627 * don't inherit from Exception directly
