Added a SIMU_EXCEPTIONS definition for allowing asserts (and on Linux all SIGFPE/SIGSGF ...) to be displayed in c9x as errors in a MessageBox. It's better than crashing the whole tool and will allow us to easily find the error thanks to the stack which will be displayed. No need to generate new hexes, nothing changed.
